Israel does it. It works. We should do it too: After every terrorist attack, the U.S. and Canada should deport every one of the terrorist's relatives.
But no: We're so tolerant, we let the radical Muslim mayor of London throw out the first pitch at the Met's game the day after an Islamic attack in the city.
Does this sound mean? I don't care.
If you're too tolerant, you're part of the problem.
