Well, I think that the reason the processes are different is because WE are different. We have a different history and a different culture. As much as people don't want to admit that, it's true. So it would make sense that anything that we create, for us and by us, would be different than anything created for and by white Americans. We are going to create for ourselves what works for us. We are different for the same reason that houses in Florida and Alaska are different: you won't see igloos in Florida. You have to create what works for YOU.
I, personally, don't think you're poking into things you shouldn't be. I hope this helps satisfy your curiousity a little bit.
