I think it's incredibly dangerous to try to group black women into generalized categories. It's impossible to answer questions like "Are Black women like 'A'" or "Do Black women do 'B'?" because there are as many different answers to this question as there are sisters on the planet.
Personally, I treat sisters the same way as I treat anyone I don't know. I'm guardedly optimistic when I meet anyone new. If I see that the person is friendly and open, then I'm friendly and open. If I see that the person has an agenda, I go along my merry way.
