What makes him a shitty person? I have not heard that and he seemed decent. Possible causes of being deemed shitty is a sliding scale depending on offense, offender, their reaction and one event or multiple?

For example Orson Scott card was such an asshole to numerous fans(especially women) he was banned from every comic and sci-fi convention. No, not kicked out. No not well you can’t come back to world con but you can go to nycc. He was blanket banned by every convention of any reasonable size. Accusations of touching/groping, spewing racist shit to crowds, insulting people and that’s how he was in public.

Now if it was like a one off event with korveak and he went overboard and called someone a slut and then apologized… Ehh, we all make mistakes. Totally different situation.
