“It’s the responsibility of the community to protect itself” is a really really dangerous way.

I’ll give you a couple of examples.

I’m catholic. I want to protect the integrity my “group”. I want all homosexuals blocked and muted.

I’m homosexual. I want my rights to be acknowledged by all the people. I want all the users that disagree blocked and muted.

If all the groups have “responsibility” (you are talking about rights, though) it’s the end of free speech and free minds.

Social polarisation comes from that and it’s one of the cancers we should try and eradicate.
