Why do black men get mad seeing black women with white men?

If black guys are so upset over this why don't they make an effort to offer a black woman some security, faithfulness and financial as well as emotional support. Which they do not. Considering many black men are fathering children by several different woman leaving them to support and raise the child on their own. He often cannot be trusted to be faithful in a relationship often he is sleeping around and running the risk of infecting her of an STD. And with over 60% of black households being are being headed by single Mothers, she cannot depend upon him for a secure and stable future together. Until more black guys are willing to step up to the plate and act like" real" men they have no right to be angry when a black woman looks for in a white guy what he is not able or willing to offer her.
