No, not all Muslims are terrorists. And not all Muslims in the US are terrorists. Clearly, very very few are. But we don’t know which are which, and the non-terrorists have a bad habit of relativizing, sympathizing with, providing aid and comfort to, and otherwise showing more concern for themselves and their tribe than the broader community.
Equally important, the non-terrorist side of the ledger adds very little to our common and collective life. We could do without any more such immigrants, and we should work to encourage self-deportation among those already here who are not firmly rooted.
Don’t expect to hear this from the Marco Rubio wing of the Republican Party any time soon.
