Opinion. From my perspective the loud mouthed morons are the ones thinking they can't say anything anymore when in fact they can. Just that bashing on minorities is not ignored anymore and people will talk back. Blizz changed that maybe preemtivly just cause it fits better.
There is a difference between beeing offensive (jimmy carr) and just being an asshole because you hate some people (antiSJW crowd)
No one is cancelling comedians for jokes. If you go the extra mile and use the n word bash on trans poeple (who are under constant ridicule by society anyway) that expect people not beeing happy.
Why should i just roll over and accept your insults? Being offended is human. Just like you are offended about people not liking the way they are treated.
