Person who imagines that they're tough:
"Grrr I can't stand all these thin-skinned [latest term sourced from insecure people on 4chan] who get upset as soon as you say something that they don't like!"

Some random person who just wants to chill:
"Hm, I think that I don't like your aggressive and insulting commentaries, regardless of whether you personally find them funny."

Person who imagines that they're tough:
"Reeeeeeeeeeeeeeeeeeeeeeee I don't like hearing that! It's so unfair that people are allowed to say things like that to me these days! Ahhhhhhhhhh"

...and then they invite Elon Musk on-stage, for unclear reasons.

If people were actually as tough as they think they are, they'd say something like: "Oh, I guess what I like isn't comfortable for other people. I'll just have to learn different behavior when in groups of strangers." That's some hardcore stoicism right there!

But instead, they actually bruise like overripe plums, or children being told that playtime is over, as soon as someone tells them, "Hey, actually, those verbal or behavioral habits that you've developed have been reconsidered in a new light, and aren't deemed okay any more in general company. Maybe save it for your private friends group. Or, perhaps, develop your personality beyond adolescence."

Also, the "Gosh, you used to be able to say anything!" crowd often tends to become miraculously more accepting of policing language expression when it's time to criticise positive commentary about a minority or other faction that they happen to personally dislike.

So, mostly, this seems to come from people who are actually upset that the world is giving them fewer and fewer sanctioned outlets for their questionable urge to constantly aggress everyone around them.

If you really can't understand why the way that you talk to your closed friends group is not acceptable when talking with total strangers who might come from all kinds of other perspectives, situations, and walks of life, then... I don't know man, I don't think other people is the real problem here.
