The point isn't to indict them on hypocrisy. The point is to post those publicly to get the backlash. That shows the Jews, Latinos, and Arabs that their "black allies" are not actually allied with them. It cracks their coalition, or prevents the coalition from forming and strengthening.
(It won't work with the albinos of course, that's just shitposting.)
There is a very real disconnect between what the different ethnic groups want. Intersectionality tries to paper that over with ideology and the language of class warfare--tell all groups the Enemy is everyone's enemy, he is generically bigoted and therefore against all ethnic groups, etc. The big stupid mistake BLM makes is laser focusing on a skin color instead of an ethnicity when they say "whiteness". That's where the division can be exploited.
Finally, there is a massive disconnect between ethnic experiences, too. You probably hear talk about redlining, impoverished districts, etc from BLM. What you don't hear about is all the Latino, Arabic, Irish, and Jewish groups that lived in those very same areas, because they weren't ethnic enclaves, they were economically poor areas. Intersectionalists/BLM not-so-secretly hates those white-ish ethnicities because they escaped the poverty over a few generations.
If you want to start a mini-race war, go up to a diverse BLM group, ask about redlining, then ask why the Latinos prospered in their city's redline district while the blacks didn't. If you really want to start trouble, ask how the Irish and the Jews made it out.
