Do you think that it's all just a cover for black males not being interested in monogamy, and with marriage being the ultimate form of monogamy their apprehension to it is understandable?
No I don't, I know PLENTY of Black men who are positive towards marriage and family vs. just a handful who are not.
The mature, logical and intelligent man (who has something to offer) is going to realize the cost/benefit analysis of multiple partners (polygamy) is NOT in his favor. That man is not going to recklessly scatter his seed or expose himself to disease. He realizes that there's no winning in roaming around aimlessly.
The intelligent man with something to offer will invest in one set of children with one wife that he's carefully selected for desirability, loyalty and other good qualities.
I don't know too many well accomplished, wealthy, educated men with multiple women... too much headache and risk to his reputation and well being. He understands the importance of BEING a good father and spouse, usually because HIS father was a good father and spouse.
But this is the norm for my world. This is how the men in my circles (family, friends, etc.) operate.
If a man has substantial assets, it's pretty easy to "hide" them in the case of divorce, but a reasonable man doesn't select a woman who he plans to divorce OR who'd take him to the cleaners in the case of divorce.
In order to win in life, one must BE reasonable and even tempered and select partners, associates who are like-minded.
I know a LOT of Black men 30s and up who are high earners, educated and prominent who avoid a perilous lifestyle because it just makes life EASIER to have genial relationships. They don't have random seeds running around and do not expose themselves to situations where they can be destroyed by some random hit & quit situation where the woman caught feelings, etc. They are extremely mindful and cautious about their inner circle.
