I ain't dissin' American culture - quite the opposite
It's just that other all-white, all-black, all-Muslim or all-whatever cultures are deficient and flawed, lacking rich crossover infusions from other cultures.
Take J. Lo for example. She combines the best of Latina culture and African-American hip-hop, expressed within the mainstream, mostly white American culture. She rocks, and is in my humble opinion the most beautiful woman in America.
Our diversity makes us stronger, homes! And that's what America is all about.
