Imagine Christian rebels saying "Jesus is great" every two seconds as they are slaughtering someone and taking close-up video of their mangled faces.. WE WOULD CALL THEM 'CRAZED FANATICS' AND 'INSANE' PEOPLE!!
No, I can't imagine that, and for good reasons.
Did you see them shooting the Russian airmen as they were parachuting down - a disgusting sight - and these are supposedly "moderates" that we're supporting?! Give me a break. They'd just as soon cut the hear out of someone and eat it on camera as would ISIS.
