There’s a lot of stupidity to unpack in that first tweet.

• “I’m called a Nazi” honestly first I’m hearing of it, so to me this is self identification
• “White culture” I imagine grimes here is saying “anything that someone who would at first glance look like a modern white person has done in all of history”
• “Brown king Cyrus the Great” I’m not racist because one of the historical figures i think about every day is brown!
• “who invented the first empire” ah yeah he MacGuyver’d one together with pure brown ingenuity, sticktoitiveness, and a plastic straw
• “Japanese icon Murasaki Shikibu[‘s] … first novel ever” tangent: perhaps this is just my own brand of degeneracy on display here: grimes is referring to “The Tale of Genji”, which I mainly know about because some of the core relationships in the book revolve around adults grooming their wards into spouses (it was a different time), which has popped up nowadays in the discourse of some fiction coming out of Japan (see Usagi Drop). So I’m tempted to project onto grimes a veneration for grooming, which kinda tracks, but it’s a stretch.
• “What if humans just loved each other?” You’re like 3 years late to former IDF member Gal Gadot’s imagine video

Gotta love the way that TESCREALnts write and how they have a tendency to generate fractally stupid things like this. There’s so much more you could say. Basically, if I could say “that’s not how any of this works” to Grimes, I would.
