What evidence do you have that Islam is not "at war with us" or does not want our destruction?
If we were at war with Islam you’d know it. We are at war with a radical, extremist faction of Islam, not all of it.
It is a religion largely trapped in the past and ruled by autocrats who’ve kept their people ignorant, desperate and poor. Once they’ve tasted freedom they rarely go back.
A religion with billions of adherents will get some percentage of radical nuts and ignorant fools, but if all billion of them were at war with civilization you’d be on the front lines yourself.
