I'm not sure what's even happening now.
Agree a lot of it is people being too thin skinned now though. That doesn't mean anything goes, some people still need calling out if they're just crossing lines too far in a given online community, but there's many out there anymore who can't even deal with debate or someone else thinking something negative about a thing they like. Too much personal identity is wrapped up in anything now and people react like it's a personal attack if you criticize something.
