I know this is long, but it is worth it. Really.
If you've seen Good Hair by Chris Rock then you'll see parallels between the beginning of this speech and what Rev. Al Sharpton mentions in the movie about how it's wrong that black people can't break into the black hair business even though the products are only used by black people. He talks about how this sort of thing would never happen in reverse (black people owning and dominating a business that only white people use).
There are so many things I love about this speech that I don't even know where to start. Simply amazing.
