I'm guessing that you're basing the fact that they're white off of the Classical art depicting them as such. The simple answer is its called "whitewashing" or if you prefer, "good old fashion racism." Look at every painting from that time period and you'll see everyone looks Swedish. For example, almost every famous painting of Jesus and he's depicted as a white guy with blonde hair despite that fact that he was born and raised in Israel. Seriously, all you're doing is trying to start a flame war.
