If someone posted the N-word, the reaction would be:

Twitter:
Ban.

Gab:
It's their god-given right to say it.

Mastodon:
If you don't ban that meme, we will isolate you from society

Nostr:
So? Just don't follow that guy.  Why should I accept a moderator for MY content, just because THAT guy is dumb?  If you think about it, taking away my freedoms over that guy, is like the very slavery you claim to be against.

BlueSky:
We've got a meeting next week to decide IF we'll either ban you, or actually federate the servers.  And then we'll send out emails apologizing on your behalf.

Farcaster:
We're developing a new decentralized-AI-moderation protocol powered by pooping-llama coin.  This revolutionary new coin is hosted on users' computers in return for rewards, and cracks down on racism.  Buy it now!

Bastyon:
The CIA kills brown-people every day and nobody cares.  You care about typing words, more than actual genocide?!  I'll use any language I have to for you to read it nigger.

 i find it funny, how some right-wing libertarians actually compare being against insults with being against freedom of speech
