Learning that about Yu-Gi-Oh tournaments just brought the biggest smile to my face! It should be an obvious no-brainer that if somebody's going out of their way to be an asshole and antagonize people, they should no longer be allowed to participate!

If you can't play nice, other people aren't going to want to play with you. We learn that as little tiny babies! I don't know why it's so hard for people to grasp. But for some people, you bring gender into it, especially non-cis genders, and it's like logic just goes out the window and is overridden by weird bigotry that helps no one.
