Re: Just as creepy:
Your first two sentences contradict one another. The nut-case absorbes ideology from their environment (i.e. not a vacuum) and twists it to justify their violence. And Jodie Foster wasn't promoting hatred of a class of people, the kid was in love with her. Contrast that with the motives of abortion clinic bombers, Oklahoma City, etc.
And the Templars job was to go out and kill Muslims to reclaim Palistine for the Catholic Church. Small surprise a wack job would get inspiration from that lot.
