Depends who you ask and their interpretation. I've been to some anti terrorism classes, put on by Muslims, who were practicing, that flat out said Islam isn't compatible with western society and it'll ruin all that's been built here if you try to integrate or commingle it.
Not my interpretation, that was a lady from Kuwait that worked for the state in counter terrorist threat assessment something or other saying it. Pretty profound.
Christianity preaches tolerance and peace and compassion, Islam has sections that kinda sorta say if you speak against their god or you're a non believer... it's kinda okay to kill you and depending on your interpretation it may actually be your duty to do so, where the whole jihad thing has its roots.
