Its hilarious how "diversity" is supposed to be about thinking beyond race/nationality/skin color, yet the measure of diversity is how many different races/nationalities/skin colors you can collect. If race does not matter, then why does "diverse" mean as many races as possible. Shouldn't it mean diversity of thought instead? If nationality does not affect personality, then why should diversity be about diversity of nations?
