As far as I am concerned, it is evil to look down on races other than your own as inferior. By the same token, I believe that it is dishonest to state that any ethnic group of any monetary status can and should be allowed to enter our nation in numbers too vast to assimilate.
There is another verse in the Bible that says "moderation in all things." I believe this is true with immigration, it is true with trade, it is true with liquor, it is true with food, it is true with sex, it is true with most things in life.
Those who advocate exclusively one idea without any possible compromise on it's full potential, are generally afraid of any challenge to their ideals because they can't support them as well as they claim to be able to.
