Why is your bar that they must be hurtful to everyone? What do you suggest to do when they direct the same behavior only a certain group in the space? You say that it does not have to be political and I agree, but what if it is? What if they see that group as a legitimate target for political reasons?
It's easier to make my point about behavior that is unquestionably harmful, like what's discussed in the article. Nothing I said can't extend to less clear-cut cases; honestly my entire point is that you should weigh decisions like this based on whether behavior is harmful to the community (or vice versa) rather than based on either side's "politics".
> What if they see that group as a legitimate target for political reasons?
It doesn't matter. I wouldn't engage with whether or not they think they're acting in a justified manner. If the behavior won't stop, the behavior is harmful, and the community would be better off without it, then sometimes you just have to kick someone out.
The reason why I say politics are a distraction is because I don't think you need to bother to explain that someone is politically incorrect or how you are less so. You can, but none of that is actually relevant in a majority of cases. Removing someone from a community is not about being more correct or about them being incorrect, it's for the good of the community (and/or the good of whoever you're removing).
For the better part of two decades I frequented a particular forum, and one of the most common reasons people tended to eventually get banned wasn't because of any particularly egregious political opinion, but because whatever opinion they held they tended to turn every thread they participated in anywhere into either a thread about that or a thread about them.
