r/whitepeopletwitter was originally created as a response to r/blackpeopletwitter, which initially focused on people posting tweets from black people, focused on issues and opinions unique to or emblematic of the lived experience and concerns of the black community.

This began to devolve into a good deal of posts highlighting negative stereotypes about black people and r/whitepeopletwitter was founded basically tongue-in-cheek, with many posts highlighting ‘white people problems’ type posts, ie, to show the kind of disconnect many online white people have due basically to their much greater likelihood to be financially secure, their much lower likelihood to deal with significant violence, police brutality, discrimination, etc.

That was all nearly a decade ago and now here on reddit and lemmy that plot has basically been lost entirely, with the current ruleset this may as well just be named /twitterpeople or even /twitter.

Again, the original idea was to kind of showcase or lampoon twitter posts from white people that show they are significantly privileged and isolated, out of touch, that sort of thing.
