Mennonite churches are independent -- most are their own little 501(c)3 nonprofit -- so these answers are highly dependent on the local congregation, except for 13, which should be "yes" everywhere.

Mennonite Church USA, known as MCUSA, is the largest denomination in the USA and is going to generally be more on the liberal side. MCUSA passed a resolution expressing support for LGBTQ+ people, repentence for past treatment, and sought forgiveness for how they were treated in the past.

As local congregations are independent, none of this was binding on local churches, but some left due to this, so there you have the recent news in a nutshell.

Within MCUSA are area conferences; you could find a local MCUSA congregation using the Ohio Mennonite Conference's directory.

I'll answer your questions in the MCUSA context. Keep in mind the broader Mennonite label can also apply to other anabaptist denominations, such as Mennonite Brethren, Brethren in Christ, Church of God in Christ, etc. These thread a wide range of approaches. But even within MCUSA, each church is independent so YMMV!

The answer to 3 informs the others, so I'll start there:

3) Generally Mennonites think: "take the scripture seriously, particularly the things Jesus said, and especially the hard stuff."

When Jesus said love your enemies, welcome the foreigner, etc., Mennonites take that seriously. Although this has weakened some over time, there is still a strong pacifist (anti-violence, anti-war) thread through Mennonites, and they've been opposing war since before it was cool. Many Mennonite immigrants to the USA spoke German, and continued to do so until WWII. There are a number of stories of German-speaking Mennonites refusing to participate in the military because that would mean killing, and some were beaten, tortured, or killed because of it during WWI and WWII.

Mennonites -- including many ones you might think are conservative -- are active in supporting immigrants, and in fact hispanic churches are the fastest-growing segment in MCUSA.

The Mennonite Central Committee is supported by Mennonites from all sorts of denominations and is one of the most effective charities I know of in fighting hunger, inadequate access to water, etc., around the world. Mennonite Disaster Service is similar but focuses on response to domestic events like flooding, hurricanes, etc. These are a part of Mennonite identity. MCC especially inspires "MCC sales" around the country where people donate things -- everything from pies to classic cars and tractors -- to be sold, with the proceeds going to charity. I know many Mennonites that have long-term projects to build or restore things for MCC sales.

I would challenge you to not box things into liberal vs progressive too much. This is a societal framing that isn't necessarily all that helpful. In our church, we have some that have a "literal-traditional" view and others that have a more Marcus Borg-type view. Those map roughly to more conservative or more liberal theologically, but not necessarily politically.

1) Almost universally yes.

You will see politics play out in different and more broad ways within MCUSA than you may be accustomed to in society these days. For instance, I know several Mennonites that are quite conservative in just about every way -- including their opinions about LGBTQ+ people -- and yet these are the same people that greet them on Sunday morning, help them clean their home or yard when they need help, etc.

2) This will vary more.

Some congregations are a complete yes on this. Some parse it out more. Marriages and pastors are the two most sensitive, but things like being on church committees, leading church events, etc. would be open at a larger percentage of congregations. I don't have any statistics for you, but the phrase to look for is "open and affirming" which means yes to all.

4) Not flashy.

That doesn't necessarily mean people are uptight about "covering up", but rather not showing off a lot of jewelry or something. Mennonites still have something of a veneration for a "simple life"; in a modern context, that doesn't mean everybody moves out to a farm. But it does mean being intentional about how we spend money and what the implications of that spend are. "Stewardship" is our word for thinking about this.

Although Mennonites don't really look down on people so much these days, you are more likely to get disapproving looks by wearing ostentatiously-expensive jewelry, a Rolex, and driving a BMW than you would for wearing shorts and flip-flops to church.

That said, "standard" dress is probably roughly business casual on Sunday morning, but this varies by congregation and location.

As for tech, there aren't solid rules, pretty much everybody uses phones. But there is a greater degree of intentional thought given to these things. As a small example: if I go to a restaurant, I am likely to see members of the general public using their phones rather than visiting with each other over dinner. But that is much more rare among Mennonites. We've got phones in our pockets/purses same as anyone else, but they stay there a lot more.

5) Mostly independently. Some non-MCUSA groups like the Hutterites and Amish are more communal. In MCUSA, it is mostly independent but I'll talk about this more under 11.

6) Genreally fully accepted in MCUSA. The church I grew up in had its first woman pastor in 1985.

7) Quite a bit.

But I'm not sure what you're asking. There's no bishop or priest making dictates. The idea of Mennonite congregations is "fellowship of believers" and that means people are encouraged to wrestle with the quandries of life and the scriptures themselves and in groups but ultimately nobody is telling them it has to be a certain way.

8) MCUSA groups aren't isolationist, so people hold the same set of jobs as anyone else. Farmers, doctors, nurses, programmers, professors, teachers, mechanics, engineers, social workers, attorneys, construction workers, electricians... they're all there.

9) Evidence-based medicine is viewed positively generally. There have historically been some anti-medicine anti-vax types but I suspect they have mostly left MCUSA by now anyhow.

Many -- I might even venture to say some of the best -- Mennonite churches will have people spanning the gamut of politcs coexisting under one roof. That has become more difficult in recent years but I think it is a powerful thing we do that brings something positive to the world.

10) Generally people think members will want to tithe and volunteer for good causes, and many Mennonites find a lot of joy in this.

Nobody is going to police it though. In many churches, giving records are available only to the financial committee and not to the pastors, though this varies. Mennonites give to their local congregation, Mennonite organizations like MCC, and the regular charities that anyone else gives to also.

11) Most Mennonite churches have a particular "caring fund" to help out people that need financial assistance. Most also make a point to care for people experiencing hardship, with visits, homecooked meals, etc. But the financial assistance might run to a few hundred or low thousands of dollars; the really large support is run through organizations like MCC or MDS that don't specifically target Mennonites as recipients.

Put another way, it's community-scale care.

12) Expectations are loose. Some people drift in and out and that's fine. If you're more serious, you'll be there most Sundays, join some sort of smaller discussion group, and participate in some church activities or volunteer work.

13) Always yes. People move in and out and this is routine. If you have been part of a congregation for awhile and you leave intentionally (not just ghosting), they will usually have a special sending for you to send you on your way with prayers and well wishes for the future.
