The remedy for this, in my opinion, is for Black men to become aware of these people. De-legitimize them and form relationships with only positive, community-centered Black women.
Heterosexual anti-Black male 'activists' will either enter Tragic Arrangements with cacs or die lonely.
Good riddance.
But you can't de-legitimize a contagious virus that will most likely infect the "positive" ones. When you do that, it will always come back to haunt you.
