Some should be deleted. "End white people" is arguably a call to violence akin to what gets the right banned.

Some lack context. The first one, for instance, still exists but it's a reply to a tweet that doesn't. It's possible this is sarcasm.

Some are clearly in bounds, like, what's Jack May's tweet saying that should be against the rules? (Third column). Or Lena Dunham arguing that we're not causing the extinction of white men? Or someone saying, "can you cite a recent example of a figure expressing racism against white people?"

And then there are all the "I hate white people" comments. Personally we're likely to disagree about them. I think it's important to contextualize history and who has power when you moderate. Punching up is different than punching down, in my opinion. It's different to say "I hate the wealthy" and "I hate the poor". "I hate a minority" is different than "I hate the majority [who have a history of being oppressors]". I think it's really tacky for these folks to tweet this, and it's not something I'd tweet, so for me it falls into a grey area. I can reasonably see your argument that these are the same as, e.g., "I hate gay people" because it's expressing hate based on identity.

If Twitter went the way of saying "expressing hate towards an group based on traits they cannot control is against the rules" I'd say that I don't think that's nuanced enough, but I could live with it.

Thanks for sharing a source, it was interesting to dive in here.
