Let's do a little thought experiment:
First, let's compare the radical Muslims of the seven countries from which Trump is trying to suspend immigration to the Nazis.
Both groups hated Jews. Many Islamic clerics in the countries named have said they want Israel wiped off the face of the earth; the Nazis held similar views.
Both groups felt that homosexuals are sick, disgusting individuals who should be persecuted.
And adherents of both movements were completely convinced of their righteousness, and superiority.
One major difference is their attitude toward women. Herman Goering never advocated cutting the clits off young girls; Joseph Goebbels never suggested that women not be allowed to go out in public with uncovered faces. And Adolf Hitler never said that women should not be allowed to drive, or attend school, or leave their houses unaccompanied by a male relative.
In any case, there are some strong parallels, even if the Islamic fundamentalists are far harsher when it comes to treatment of women.
Now, let's imagine that Germany and Austria were still dominated by the Nazis -- and that many of them want to emigrate to the US. And, let's say that the political dividing lines in America regarding the immigration controversy were roughly the same as they are now.
What would the liberals be saying? Ignore for the moment the fact that the Left's favorite insult these days is "Nazi" -- since the Nazis, in both spirit and belief, did have much in common with today's Islamic fundamentalists.
Would they call people opposed to immigration "Naziphobics," as if they had some sort of weird mental disease?
Would they say that we shouldn't discriminate on the basis of creed, or persecute those poor Nazis for their beliefs?
Would they tell the anti-immigration forces that "that's not who we are?"
Would they constantly remind us that we are a nation of immigrants?
Would they have sanctuary cities catering to illegal Nazi immigrants?
Would they accuse those opposed to more immigration of being "haters?"
After all, this is effectively what's going on right now, except for that minor difference of the Islamic attitude toward women.
Think of this parallel the next time you hear a liberal become hysterical over Trump's proposed immigration ban.
