Thus begins yet another unendable initiative. Differences exist, therefore we say there could be inequality. Since there could be inequality, better to consciously bias against the alleged inequality, just in case the inequality actually exists. And since it's impossible to prove its nonexistence, better to simply state that it exists. After all, there HAS to exist some bias somewhere, no matter how significant. It's safer to think this way because you avoid being labeled as "against equality", and can enjoy life with the other "enlightened".
I just call it pure cowardice.
