A bit late to the party, but Wendy Xu/AngrygirLcomics is also a bit of a cow in YA twitter herself (crossover with comics twitter, too). She's relatively unremarkable from the rest of the fold: likes to virtue signal and scream at yts like any other of these people, and talks about how hard it is being an Asian woman in Trump's America. It's been a while since I've paid attention to her, but she worked for some publisher in NYC yet somehow managed to not live in a shithole with 3 other people--oh, wait, her father is some kind of lawyer. Of course she comes from money but never really talks about her financial privilege. She also has a 6-figure deal from HarperCollins for 3 GNs). Despite claiming ultra progressiveness she will tongue Phillip Pullman's asshole at any given moment and even got one of those fancy daemon statues that went out to promote the His Dark Materials show.FWIW, the closest to direct and specific claims apparently came from this account: https://twitter.com/AngrygirLcomics ; now in lockdown so I can't check it. She is also a close associate/BFF to ... none other than the angry ex-gf referenced above. (See her account description.) Doubtless her impartiality is beyond doubt, though. A gentleman could hardly think otherwise.
I think her most memorable moment was a few years ago when she was screeching about how calling a mung bean-based tofu "tofu" was culturally appropriation and she was losing her shit (the Chinese character for soybean is in the name). Wished I had saved it.
