Yeah, this ain't it.
White people and black people have had different histories, different experiences, purely because of their race and the privileges (for white people), or disadvantages (for black people) that come with folks purely on their skin color.
No one knows black people better than black people. Thus black people are the most appropriate for telling black people's stories. We've had a LONG history of white people telling black people's stories and let's face it, fucking sucking at it.
THEN we get to opportunity. We've had a long history of an agency, company, employer, what have you, hiring a white person over a black person PURELY because of racial bias. In the western world (where of course Hollywood and other BIG places are generally located), are ruled by white people. So naturally, white people have historically been shall we say, not exactly gracious in why they'd pick a white person to do, really, anything when even a black person beside them could do it even better. It's about giving black people opportunities that they've been denied for generations.
In the 21st century we are moving to a new generation that is bringing the power black people, and other minorities, were denied for far too long. It's about time we give black writers, black actors, black musicians, what have you the opportunity to bring their vision and talents to the forefront and not have a white person get in the way or take credit for that, because white people have fucking done that for decades.
So yeah, let black people do their thing. Let them tell their stories and not have white people keep trying to tell their stories for them.
