very true - a billion jihadi would run the place - except once they took over the world they’d start fighting with themselves, blowing themselves up and cutting off their daughters’ heads to demonstrate how honorable they are. Like orcs in Tolkein’s world, there’s a long-term downside to being blood-thirsty, hateful animals.
There are lots of people walking the streets who fit that description. I don't know if they comprise a larger or smaller portion of the jihadi/muslim ratio.
I have to be perfectly real: I've known mulsims who are tremendous people.
