Why is it that all the terrorists are ultra-conservatives?

Answer 1

That depends on how you define "conservative."

If you want to compare some kind of Christian philosophy to the Islamic terrorists you'd first have to find a group of Christians who cut off a person's hand for stealing a loaf of bread & wants to end the life of anyone who doesn't agree with that philosophy.

Find such a group today & you will have a fair comparison.
