I grew up with an emotionally abusive father, and it took me a while to understand how that impacted my perception of men. With boys, it's absolutely critical that mothers are nurturing. You may not help it but you get triggered as soon as a woman exhibits just an iota of what you witnessed as a child growing up. This woman could be completely innocent. You may just see a black woman with weave in her hair and assume all kinds of shyt while knowing nothing about her life. She maybe wearing that style for the first time, or trying something new, or who cares if she regularly goes to the salon, that's her bizness, but one or two things make you think of your mother, who no doubt influenced your sisters as well, and that tarnishes your image of all black women. Deal with your issues. We talk about black fathers influencing their sons - this is important - but a mother's belief and faith in her son shapes his confidence and his ability to have healthy stable relationships.
I don't need a man thing is the byproduct of dysfunctional communities where there's no wealth and where people are constantly on a hustle and there's no stability. It's a symptom of a larger problem, not the cause. Black people are ridiculously hurtful to each other and will use all manner of tools to get at each other - from comments about skin colour, calling each other every manner of name in the dictionary and so on because many black communities are disempowered and have been so for generations. You see the same generational dysfunction in some white communities , even in Europe. It's not a black thing, but a human thing. Environment shapes culture. Understanding the dynamics can help heal the pain somewhat. And it is critical that you understand all women are not your mother and you cannot lash out at millions of other human beings because of your mother's flaws.
