People consume crap. Tyler Perry makes crap.
This isn't art, it's commerce: Tyler Perry creates products that a lot of people "buy".
It doesn't mean that those products are good or important.
It also doesn't mean that he doesn't promote negative stereotypes, separatism, or racism.
It just mean that there's a market for negative stereotypes, separatism and racism that mainstream filmmakers haven't learned how to tap into yet.
