The controversy over Donald Trump's latest statement about Muslims deserves comment. In case anyone hasn't heard, he said we should not allow any Muslim immigrants into this country. (He actually worded it as, “Donald J. Trump is calling for...” I shall not at present comment on his tendency to describe his statements in the third person instead of just saying, “I am calling for...” However the psychologists may be able to make something of that.)
While we clearly need to keep terrorists out of our country, and his statement has created justifiable controversy, that controversy has not yet mentioned one salient fact: Trump's proposal is essentially unworkable. To do it, we either have to stop all immigration, or find some way to determine who is and is not a Muslim. No, we cannot just ask them.
The sad fact is that the terrorists who would enter our country are world class liars. To them, lying in pursuit of their objectives is not only acceptable, it is expected, regarded as a positive good. The terrorists wanting to come to our shores will simply claim to be Christian, or even atheist or Jewish, and we have no way to determine if they are telling the truth. Trump's proposal would keep out the honest Muslims while allowing in the fanatic terrorists.
