If they were muslims you'd call them terrorists or muslim extremists. If they're american they're most likely (99.999%) christian so let's call them christian extremists. In germany i don't know if you guys buy that christian superman tale so we'll call them white devil extremists. When they kill someone besides just attack a camp then i fully expect you all to call them terrorists because that's what they are or will be. I already know them to be terrorists so i dont' worry about that but you people need to be convinced. Remove your prejudice and call them what they are. Terrorists and kill them like you do the muslim terrorists.
I'm muslim and have already denounced the muslim extremists and terrorists. So welcome my terrorist denouncing and future terrorists killing brothers welcome.
