Taken from my own comment:
There is a disturbing trend going on where melting pot theory proponents assume that if you believe that X group probably made the country a worse place when they tried to assimilate with a country that has a philosophy totally foreign to theirs, you really think X group is inferior to you and they should all be deported or killed or something.
Nobody seems to be catching the obvious point: That melting pot theory proponents apparently believe people who think differently than Americans are untermenschen. In fact, this is so self-evident to them that they literally can’t conceive of anybody thinking differently.
Those willing to doff their hats to the king have the souls of slaves, after all. Or so I’ve been told.
