Yeah, and so are the far-left, but I only see you trashing the far-right. There are plenty of people who have shitty ideologies, (namely the far left on the other side of the spectrum who believe they need to kill off everyone who don't agree with them)

I mean, let's pretend you somehow did allow nazis to be arrested on the basis that "they're gonna do bad"

Okay sure. So are you going to recruit facebook to spy on each and every one of their users? Are you going to force google to single out users who search keywords like fascism and nazis? I mean, it's possible, the NSA did it, but we all saw how much of a shitstorm that was.

Are we going to go after every single ideology we don't like? 

I mean, not to mention scouring the internet is a very tedious job and you're only really going to catch the very outspoken ones and then drive the rest underground, to which the ideology will still exist.

Also, the american government once discriminated against basically every non-white, but I don't see you calling for all of their heads.

Moral Relativism is a very flawed theory. 

It implies that you cannot judge others, and using that point, one could argue you can't be mad at the nazis for growing up in a country that hated the jews, blacks, slavs, and so many others? 

Just... no. It's just a cop out.

You can make judgements and compare moralities. 

Cultures have shared values as well, so relativism only works up to a point.
