EDIT: no, I don't sympathize with nazis (neither I sympathize with those who call everyone nazi when they're losing an argument ;)
The funniest part is when two instances federate, but the userbases of both instances want to defederate with each other immediately afterwards lol.
Go back to whichever 14 year old infested, fake communist, edgelord hideout you crawled out of.
I think they're mainly quick to defederate because they don't want to burn out their mods.
Conflict and drama means lots of work for them so I can see it being an easy choice. Personally I'm happy my instance isn't too trigger happy with it
Forreal your instance might be the one I'm most confused by, you've got like a 50/50 split of chill people who are okay with conversation and people who drop slurs and reply to any attempt at engagement in memes and 
gotcha one-liners.
If the 'thing you dont agree' with is hate speech or shit promotting violence for example that's the only sane option you have lol
Yes. Tolerance should not extend to intolerance, and intolerance should never be a thing we tolerate.
Fascists and child porn spammers may have rights somewhere, but not in my world.
True but.
It reminds me of this discussion I had on Reddit with a person who said it was okay to punch a Nazi, just like that. Walk up to them l, punch.
I start with that Nazi's don't really exist, and if someone has intolerant ideas them maybe it's better to talk them out of those ideas instead of reinforcing them.
This discussion took a few messages until it ended with this person calling me a Nazi and threateni to punch me if he ever saw me, just and only because o disagreed with unjustified violence against intolerant people
This person was just as intolerant as a Nazi themselves and didn't even realize it.
