race mixing as in white and black, yellow and whiteerm.. no, race-mixing destroys diversity rather than promotes it. Mixing every race until we look the same, speak the same language and share the SAME universal culture is NOT diversity! It takes the "multi" from multi-culturalism.
Every year hundreds of languages go extinct!
race mixing as in ppl from different nationalities/ethnicities?
a turk and a greek get together, same race but different ethnicity.
a japanese and a chinese get together, same race but different ethnicity
but since we all came from africa, don't u think that everyone is technically a mutt?
