Dowding it seems that cabby has learned during his respectable education history that the real americans created the country and the eurotrash immigrants just meddled along with that.
They were more of a nuisance which unfortunately had to be dealt with. So there were the real (tm) americans, native americans who originally lived in the reservates, bunch of drunks you know.. and the fortune seeking euros that later on returned to save the homecontinent because the genetic filth that wasn't smart enough to move away were left struggling with Hitler.
