I have always strongly suspected this as well. Not in every case, but definitely some of the loudest ones need to be vetted for domestic abuse in their past for example.
As for the 23 year old, he basically did the emotional equivalent of standing on one street corner in one American city and declaring that all the women who passed by were unworthy, so he’s moving to a new country. he cannot possibly know that about black women. All the women I know know how to cook, even the youngest ones, so not cooking is a lie. What I suspect he means is they are not submissive enough to him.
So we’ve reached the point in black culture where some black men just don’t want strong partners who will be capable of fighting by their side in a pinch? Or are there voices simply being elevated by social media.
