Why don't black men pay alimony ? Because they never put a ring on it.
Do you think that black men don't marry their partners?
Yes, black men don't get married because they are criminals and in prison.
Marriage is a partnership and not everyone wants to get married, race has nothing to do with it. Many black men support their families and get married and they are not criminals. It's difficult to make a generalization like that.
That is a fact and there is nothing you can do about it.
I am suspicious of your statistics, because there is a lot of evidence that within each race, there is a similar percentage of people who are criminals. I do not think it is true that black people are more likely to commit crimes than any other race. Even if it is true, making a joke about it is not an appropriate way to address the issue.
