I think there is a communication problem with brehs and the sistas. For example, when I used to work retail me and some of my coworkers like 2 Italian Chicks and one PR chick all used to sit and discuss Game of Thrones (Yeah, I know Cac shyt lol).
We be there talkin bout the show, on some "Did you see the last episode?"

type shyt. Talking bout different scenarios, joking and laughing and shyt
I find often times brehs and the sistas don't have these simple kind of convos. It might just be me but I can't think of many times where I would see a Breh just talking about shyt like a TV show, or the weather, or some random topic with a sista and just laughing and having a good time.
This is how brehs like a Donald Glover end up with non-Black women because they end up discussing regular shyt and just chilling, basically I feel like the kind of convos the brehs have with sistas are limited to a certain degree. It's like there's always some weird tension between BM and BW if you ask me
