@mietze I considered it for a while? Thing is, I would crack down on not just things like Tyche did, but also the quick-labeling of people as racist/sexist/etc. Calling out a behavior or action as a *ist act is helpful and necessary, I believe, and can lead to productive discussion, but labeling human beings tends to get people to dig their heels in and escalate or dismiss what's being said out of defensiveness.
I grok the intellectual argument that we are all *ist in ingrained ways by society, and we should examine that, but getting people to engage in the hard work of self-examination of these biases in good faith and trying to better themselves in these important ways is difficult once the defensive reaction button is pressed. Most folks are also legitimately unaware of these interpretations of the language, which are more academic than common parlance, and will assume 'you're sexist' means they're regularly engaging in sexual harassment or active, conscious misogyny, etc., and I get why people freak out and go on the defensive when that's how they're interpreting the statement. Extra unfortunate is that it's most common in people who do make an effort, and the defensiveness comes from 'I know I am making an effort to not be that kind of person!' and they don't fully understand why it's being said.
On conscious *ist behavior, trolling, bullying, or harassment, there would be no leeway or understanding afforded there. 'I was just kidding!'? Nope. Get a better sense of humor. 
Pretty sure that'd go over like a lead balloon, which is something I find sad for a number of reasons.
