I think the far more worrying trend is trying to silence anyone with different political ideologies. Like their handpicked example of a user discussing "'destroý' Islam". Note, they added the quotes around destroy. But the actual content is reasonably thoughtful discussion of appointed supreme court judges and only claims "to end radical islam".
I drew the line at bad behaviour, which usually came in response to unpopular opinions. In other words, I left conservative comments and deleted angry personal attacks in response to them.
Some people did not get it. We had a biweekly "where are the mods" rant. They accused mods of siding with "the Nazis". By that they meant anyone who said anything a conservative person might agree with. Guilt by association.
This is how I learned the term concern trolling, which I understand as someone listening to your arguments in order to debate them. In other words, a debate. Some people were not having it.
We get hiveminds because that's what people ask for.
