Worth noting that Latinos are themselves colonizers (well, at least of mixed ancestry). Latinx is still stupid and condescending, but framing it as colonialism is a bit reductive.

In the early 1800s my Latin American country still had separate towns for different ethnicities, but today most of us are of mixed ancestry.

Does the modern definition of colonizer include mixed ancestry descendants too?

Considering how many white americans can cite 1/4-1/8 native american descent, yeah.

Or maybe that proves the point that just because you had ancestors of a certain stripe does not mean you are of that kind.

Latinx is not even an English word, it is a made-up word. It is not language evolution but an attempt at language revolution which fortunately seems to have failed thus far. May it keep on failing and may it - and the multitude of other attempts - serve as a warning that Newspeak better remain in the dystopic novels from which it often seems to originate.
