I think Spike was calling for 2 things:
Mainly: awareness and respect for a culture/people who historically are oppressed and told their culture is illegitimate/lesser.
Secondly: awareness that there's a broken institution and a call/desire for that institution to be fixed, to stop only caring about white neighborhoods, to care about everything, and to (like the gentrifiers) be aware and respectful of those cultures who're already there.
Respect for different cultures is the realest solution you can give, especially if that respect runs deep enough to hit 'the system'
No no no no no a million times no that's not a thing dont be stupid
edit: I just want to reiterate that racism against whites (or: reverse racism) is not a thing. It's crazy. Your implication that he 'just wanted white people out' is terrible.
They came into a black neighborhood: fine. nothing wrong with that
But then: they, with a total lack of awareness, trod upon their culture. That's bad.
And then: because more white people are there, it becomes a "nicer neighborhood", and rent goes up. That's bad.
And THEN: Some of the lower income black families are forced to move from their homes, more white people come in, and after years of struggle to improve their situation, neighborhood, etc, it's ONLY WHEN THEY LEAVE THAT THE INSTITUTION STARTS CLEANING THE PLACE UP
And you get mad at Spike because he said fuck that? Fuck you, dude.
