Insofar as we can separate the Jihadis and treasonous Sharia supporters, I favor exiling them. I think we have grounds to get rid of people who advocate the overthrow of America.
The difficulty is determining who is whom. I am not willing to throw out a large bunch of patriotic Americans who happen to be Muslim in order to get rid of their noxious brethren.
If there were a good way to separate them, then fine.
Otherwise, you’d be lining up just a different group of people for the cattle cars. We Jews wouldn’t support that against our opponents.
It’d be easy, anyone who preaches treason and those who go to here those sermons.
