Most fragile white person.

I'd respectfully disagree. The X people Twitter communities are for people who grew up within the context of their race to talk about things that are relevant to that race.

A lot of blackpeopletwitter posts wouldn't "do well" (receive upvotes) if they are presented to a general (mixed race) audience, simply because the majority of people may not relate to it. Therefore, there is a demand for black voices to speak to black voices. This extends to all races--my wife is Mexican, so I'll hop into latinopeopletwitter on occasion.

So why stop whitepeopletwitter? Unless there's something exclusionary/ problematic/ Nazi-adjacent happening, it seems like a good way for stereotypical white peeps to make dumb jokes about meatloaf. Micro blog memes has a similar-ish vibe, but that's mostly because the site is mostly white lol.

"But there's no such thing as "white culture" in the same way that black culture in America developed from having their cultural identity taken away, and being forced to create new traditions to navigate slavery, civil rights, and modern America! They already have cultural traditions tied to their country of origin, like Germans or Irish celebrations!"

Yup! But the concept of "whiteness" is becoming a thing, and it's fun to make memes about. That's all.
