Among other genres.
Maybe your mental model of people drawing themselves with "slanted eye representation" is more specific in nature?
I haven't seen the other tropes you've mentioned though.
It doesn't strike you as odd that in this whole enormous controversy which has consumed right wing media all week and driven this thousand+ comment thread to the top of HN...
... that no one thought to show you the actual artwork in question, and that you never looked it up for yourself?
Seriously, it's pretty bad. Go look.
My prior comment was in response to this gap.
With regards to the controversy stirred up by right-wing propaganda, Aesop's fable of the bull and the gnat applies for me.
Peace.
The kind of ridiculous physical caricature we see in this kind of artwork (slanted eyes and buck teeth on asians, long arms, huge lips and a completely non-representative chimpanzee circle around the mouth on africans, etc...) only makes sense when viewed from outside, in the "look at these strange and alien people" sense. No one drawing themself reaches for tropes like this.
