you can go ahead and block challenging ideas from being seen so you dont hurt your feefees all you want when you have administrative powers
when you don't, suck it up and close the tab
1) There are ways to express your 'challenging ideas' without being a richard to people
2) In most cases, being a richard to people
is punishable, and in this case, the richards are retaliating because they were punished and can't pick on SJWs anymore
3) Or you can talk to an administrator and point out the fact that someone is stirring up stuff and harassing people and
they can execute the punishment.
You make the Internet sound like a lawless desert where everyone is allowed to do and say whatever the forget they want without receiving consequences. You make the Internet sound like an unsafe place.
