I don't think banning an entire religion is fair or even logistically possible, beyond that how would you even implement such a "ban"? For something seeking to do harm specifically in retaliation of such a policy, it would be pretty easy to simply get a fake ID, there are plenty of Muslims who are fair skinned and have light eyes, so the whole "lets profile the guy who looks like Bin Laden" wouldn't necessarily work either.
Implimentation of such a policy would likely directly lead to more attacks not less, as it would make the US a bigger target and it would shame hundreds of thousands of completely innocent people and likely also fuel more hate crimes.
There should be greater vetting of people and a better screening process, I would agree with that, but it should be done in a way that respects the dignity of all people. Creating a system that antagonizes people and humilates them in public isn't going to help anyone. But you can't stop every crime from happening.
We don't ban cell phones even though they kill hundreds of people every year in traffic accidents, terrorism in the US kills maybe 5-10 people on average/year in the US. It's a problem for sure, but it also helps to have some perspective.
