…What? This person is not shoehorning in any conversation about anything.
They are saying they are exactly the kind of person who could identify themself as latinx and that they hate it and prefer latine.
You are arguing against things people are not actually saying.
“I’m a black person and I think we should be talking about ethics in game journalism.”
I think its closer to

to which you replied
“Theodore Roosevelt gave a speech where he said that we should identify as simply Americans, but he was actually racist against black people so therefore historilinguistically we should use the term african american.”
