I didn't pretend anything of the sort.  Who would pretend that those acts you mentioned didn't occur?

I certainly didn't.  I want measures taken to stop all religious extremism.

Don't you?

If some of these attacks can be prevented by increasing immigration vetting for people from radicalized nations, I'm all for it.   

I don't get these arguments about Christian's committing crimes, as if there is some policy that allows it.  Or that you suggest that I allow it.  Or that two wrongs somehow make a right.   Or that since Christians do commit terrorism, we should be ashamed to vet people from radicalized Muslim nations.

In other words, your argument makes no intellectual or moral sense to me whatsoever.
