Same thing happens in the Jewish community. The fastest guy to make a guy seem desirable to the thin white women in the room is for a woman of color to so much as talk to him and for him to seem interested.
What gets really appalling though is how often men seem perfectly willing to go along with it and accept attention from whatever woman is giving it. They don’t seem to understand what women are doing or how women are competing with each other. Or they don’t care, so long as they get the attention they want.
I’m so sorry it’s like this. Women can be so cruel and there is no cruelty like entitled white women.
