I've seen cis latine people and even binary trans latine people complain about it, and latine as well, personally. Navigating the discourse about it is kinda hell lol.

I definitely have, but it's the same sort of person who complains about singular they.

I've never heard a white person pronounce it correctly either.

ive heard people call latinx ugly and prefer latine or latinu. latinu is more common in brazil, latine (-e) is considered standard by the governments of cuba and argentina

Come to my country and you'll see people get knocked out over using it
