Which community have you been a part of, online or otherwise, where "flagrant violation of the norms" doesn't carry the potential for expulsion?

Without a written code of conduct, there are still values, views, and norms, usually created and run by the most disruptive members who are free to behave in any way they see fit and ostracize those who that behavior hurts.

>that doesn't fit their views, whatever that may be.

Their "view" is that sexual harassment is not something they want on their platform.

Americans come from a country where, in living memory, having a different colour skin removed whole areas of your legal rights. Interracial marriage was banned in several states until roughly the time of the moon landings. This is why Americans are rather touchy about people making light of racism.

There is a middle ground between "sending people to camps for a wrong joke" and "no one should be held accountable for any of their actions if they claim they are jokes"

>someone else's wrong joke

>punishing people for jokes

Again, we're talking about sexual harassment and racism. It's important not to leave that part out.
