See, I like that different types of black women are being positively represented. Where else do they get to be superheroes?
I don't necessarily agree with the "loud" or "Ebonics" observations either, at least not from the stereotyping angle. They definitely come off as more "urban" (hate that term), but they're both clearly intelligent, reasonable, and of good character. They're also presented as physically attractive. This all contradicts the stereotype of black women who don't "act white" (REALLY hate that term, not that you used it).
Surely you don't want all black women on tv (or the CW) to be from non-black suburbs lol
