I have never seen any research proving communities with more women are more violent. That is a claim you are making up.
And you're making it up because you desperately need to blame women for the actions of Black men -- heaven forbid we demand Black male accountability!
This deflection is childlike, cowardly, and irresponsible.
Unemployment, poor education, redlining, and economic (white) flight create the impoverished conditions of South Chicago, and young Black men become pawns of self-genocide. The causation is institutional and systemic, but there is also the factor of chosen and promoted attitudes and behaviors.
Evoking alternate realities where Black women are the culprits of mass Black death doesn't help us fix real issues in this reality.
