Being an asshole isn’t cheating. Plus, if we’re gonna throw out every chess player who is an asshole we’re gonna be throwing out a lot of them.
e; And there’s no practical way to go after assholes here without harming a lot of innocent non-assholes in the process.
Also, if your goal is just to avoid any controversies and arguments, wait until someone accuses their opponent of being trans to try to get them thrown out.
It’s a stupid rule that solves a non-issue while creating a lot more problems.
