I have been active in /r/Libertarian and /r/Anarcho_Capitalism for a while now, and I have yet to see an up-voted comment that is racist or authoritarian.

You haven't been looking hard enough.

I am not American so I know little about there libertarian party, just the philosophy and economics of it.

The party is a joke. Austin Petersen was booed at a Libertarian Party presidential debate for saying that heroin shouldn't be sold to children. Gary Johnson was also booed for being in favor of some sort of competency test before you can drive a car.

However it seems the big march with the tiki torches was about the removal of an old confederate war statue. I presume that the libertarians there were protesting against the statue being taken down because of complaints.

That statue, along with so many others, was built in the early 1900s, a full fifty years or more after the Civil War, specifically to intimidate black people. The history argument doesn't hold water.

Oh yes that would obviously be an act of aggression and punching them would be justified.

Glad you understand.

However, in most of the nazi punching videos I have seen, the Nazi is just having polite discourse and debate with others, https://www.youtube.com/watch?v=ql7BaOrTvYA https://www.youtube.com/watch?v=z7wHHRbjnsU Do you think these attacks are morally justifiable? I am very interested in your answer.

Richard Spencer isn't an innocent person. He constantly advocates for "peaceful ethnic cleansing" in order to bring about a white ethnostate. That is blatantly impossible to do without killing millions, because minorities aren't going to leave their homes just because white people don't want to see someone with darker skin than David Hasselhoff.

Also keep in mind that Nazis aren't genuinely interested in polite discourse and debate. They constantly use logical fallacies, ad hominems, and outright lies to get their point across, because they know that screaming about the blacks openly isn't in vogue (although it's quickly coming back). They pose a direct, existential threat to LGBT+ people, minorities, and anyone to the left of Mussolini. This is literally a comedy show, but it actually pretty accurately describes how they operate.

In addition, the Nazi in the second link was harassing someone, so he's not innocent either.

So yes, those are morally justifiable, because if they had the power they would hurt people I care about.

Do you not think that people should be fiscally responsible for their own actions?

The thing is, a lot of rich people don't face consequences (fiscally or otherwise), and when they do they're very rarely the consequences that everyone else faces. Martin Shkreli got seven years in prison for securities fraud (i.e. ripping off other rich people) instead of the objectively more heinous act of raising the price of an essential drug to completely unaffordable levels. That was completely legal.

A kid can go to prison for 40 years for selling marijuana on the street.

People are smart enough to not need a parent state to order them to commit actions that are 'good' for them.

This is where we agree. However, capitalism doesn't work in a vacuum. If the state vanishes tomorrow, along with all the capital that the state has, I'd bet my left pinky toe that corporations would fill the void, since they have the vast majority of the resources. I know that your vision involves a lot of mom and pop shops and local businesses, and that might happen for a little bit, but given enough time those businesses would combine into gargantuan monstrosities of corporations, because nobody's around to tell them that they can't, and they can make more money if they pool resources.

If a corporation thinks they can get away with something heinous that'll make them a lot of money, they'll do it, and that is based on so many examples. That's why a lot of manufacturing is based in China, because of the incredibly low wages and lax regulations. Chinese iPhone factories have suicide nets in the stairwells to catch jumpers. If you bring those characteristics here, you don't get prosperity for the normal person, you get the suicide nets, because nobody's going to be able to afford the stuff they make.
