From the links in this article: he called Zoe Quinn a c-word (which many people have), tweeted "It's ok to be white." (which it is), and says he doesn't regard biological men who identify as women are women (which is a fairly common belief). QAnon is a weird conspiracy theory, but the rest don't strike me as particularly odd.

It's probably worth having a Code of Conduct which requires explicit hard left belief systems if you're going to exclude people with mainstream beliefs.
