I have known good black men. One of them is a very close friend of mine. He has never cheated on anyone, has no "baby mammas", works full time, has never been in jail, has a Master's degree, goes to church...
His brother recently married a woman with a young daughter, and when a predator tried to hurt the little girl he went ballistic as he and his wife worked to protect their child. And yes, he is her father now, since the biological father is not involved.
I have known other really wonderful black men. BUT... I have also seen black men be abusive to black women while being overly friendly to white women. I've also known of black men who have abandoned their children. Actually, lots of them. What you have described is undeniable to anyone who has eyes and half a brain.
