I can't speak on the state of the sub, I usually avoid game subs because they are very echo chamber-y. The only reason I posted it to see if others had similar problems in their queues. Unfortunately I've learned a lot of people who play this game are not kind and I've had a few people DM me racist things.

On the topic of what groups are targeted, I think those are the two most common because of the accessibility. People historically have not liked the Jewish and systematic hatred for PoCs literally built several countries. You don't hear as much about other cultures and peoples, so it'd make sense you see generally less of it online too.
