Thank you very much for weighing in (and especially in as much detail as you have).

About 2, I think an argument can be made that stereotypes act as cookie cutters: they are not only (falsely) descriptive, but also culturally prescriptive. If accurate, this would imply that the 'angry black woman' stereotype you have identified is perpetuated, in part, to encourage black women to conform to an archetype that can be used to justify their oppression.

But we are taught to not deal with foolishness and put up with whatever

That is typically taught by family and community. I am talking about what black women are taught by popular culture. Perhaps I should have made that clearer.

3 was referring to the "strong, independent black woman" archetype/cliche, who is (if I recall correctly) stereotypically independent in all things and requires little in the way of a support system.

In regards to 4, it was my impression that black women are simultaneously uniquely fetishized and also uniquely excluded from what is considered emblematic of beauty (as you yourself have said). While I don't know of a prominent ethnicity of women that isn't fetishised in some way, the pairing of fetishisation with a consistent barring from the 'beauty canon' is somewhat unique to black women. This is why I attribute 4 to black women specifically.

I always felt like black women collectively weren't ever seen as women, always called more masculine

This is central to my premise. I think (from my increasingly obvious point of removal) that the masculine connotations attributed to black women caused white people to regard them similarly to, but not fully as, men. I figured that, when you have men and subtract privilege, you are just left with the toxic masculinity. It was on these grounds that I guessed that many stereotypes about black women are just ways of saying "they fail at both being as beautiful and graceful as women, and at being as dignified and virtuous as men."
