While I see where you're coming from, you're missing McCain's point here.
While I'm not saying I agree, McCain's idea is "try getting a better job or house if islam takes over and wins the war on terror and you die in a burning building."
Is that the biggest threat to most people? Many are more concerned with their kids, job, house, etc. But that's McCain's point from what I gather
"Compromise, hell! That's what has happened to us all down the line -- and that's the very cause of our woes. If freedom is right and tyranny is wrong, why should those who believe in freedom treat it as if it were a roll of bologna to be bartered a slice at a time?"
