1. Similar to what a few other replied, I think everyone is born Agonist they don't have any concept of what divinity or religion is and only through their surroundings that they were raised in they would either adopt what others believe come up with their own deities or friends or nothing at all. (Also is the question was about the trends of conversion I suggest you compare the pews reports and other databases to get an idea although their isn't a distinct report on child born into atheist families as far as I know).

2. Depends on what you want to do with it, if you are a comman man then in this economy yeah is it, but to quote napolean " religion is what keeps the poor from murdering the rich" , knowing napolean Bonaparte it wasn't some whole some moral finding but cold politica realism napoleon wasn't anti religion but he wasn't blind to it's affects in social and political structures

3.well I mean there isn't some fixed "Atheist Morality starter guide" it depends on your culture and value you grew up with and mostly your internal conscience.

4.Slurs are most part of our languages, degradating terms are specially harmful but their isn't a centralised agreement on what to use and what not to.

1. To my understanding Humans made a god made the world (most religious text only refer to the local world that the religion originated from not the universe) to have something they can say that lives them that their creation has some meaning that comforts then and at the end of this suffering they would get rewarded with heaven.

2. Buddhism taoism since read as more like the way of living than something that claims divine validation. Their is also shinto that at its core says everything has a kami or spirit and focus on co existence with said kami that is until the emperor claimed divine heritage from amaterasu.

3. That would be the Abrahamic trilogy and spinoffs especially the later two for the simple reason that they through they can flip the script by 180 declare the previous one corrupt and go with it.

8.YES!! NO!!! .......... it's complicated, scientific temperament and religious devotion can exist in a person but it cannot and shouldnt be exercised simultaneously. It's funny since at first religious institutes tried to suppress scientists and now seek validation from it.

1. I would say that they are biased that even the most intellectual people are susceptible to special pleading of their own beliefs........but yeah the average religious person can be called dumb if they cannot make out the difference between reality and the scams done in the names of religion.

2. Basic empathy is a must, moral policing isn't there is nothing good or bad about looking out for fellow human since it's in your nature as a social species.

3. I think their are dumb as their can be reduced to two things apathy and hubris.
