True, true. Back on topic. Anyhow, what I'm trying to say is that even if we did do it for 600+ years, and we did, why does that give them the right to do it to us? To quote the Bible on one of the more sensable and wise of its sayings in it, two wrongs do not make a right.
Just becouse we wronged the other races with bigotry doesn't make them right for doing the same. Only when everybody stops doing it, and bands together as one race, will we be able to extract the full potential of humanity.
