Incivility is always just a transparent excuse to censor content someone in power doesn't like. It happens to me all the time on Lemmy, of all places. It's not a platform problem, it's just the human condition.

People need to keep their worldviews stable to keep the narratives of their lives straight, and toppling them over causes extreme psychological damage, so I actually don't blame them for doing that. It is just self-protection for them, even if it is harmful for everyone else.
