Thank you, Lazamatz. I hope it gets read and shared - I just found it, and the credit goes to the poster at Conservative Treehouse.
I wish we could find a way to deport Muslims who are already here, as 25% believe it is desirable to kill us, and 50% want to establish Sharia law. This is from a couple of polls, which could be questioned, of course, considering how unreliable polling is these days.
But, how could we deport someone like the murdering male in San Bernadino, who was born here?
Is there any historical precedent for dealing with traitors within, other than jailing them?
