She has been a stubborn, defensive, fragile, manipulative, police apologizing gaslighter for decades whose always considered her and her circle good Liberals. We see each other on average for a week a year. The only Black people she knows are her biracial friend, who is treated relatively well and did not know her Black family, and the friend's deadbeat alcoholic husband who she avoids for toxic reasons.
She finally realizes she is harmfully ignorant, knows nothing about race, and should fall back and listen to Black people and other minority groups. We just had discussion over a racially insensitive post she made on FB, I picked her brain about it and she didn't use her usual defense mechanisms and actually listened. She asked for resources to consume on her own bc she doesn't substantively know any other minorities.
I think Netflix has a few good opinions too, like 13th, LA 92 and so on.
Thanks. I'm going to also suggest OJ Made in America down the line. I think it does a good job of explaining some racial dynamics in LA and America.
