Ive wondered the same thing for quite some time now...i've noticed when christian "activists" fight for something it is a joke. even by fellow christians it is seen as a joke, let a christian organization fight against something on television, let a christian organization fight for religion to be taught back in schools or to get a nativity scene put in the middle of their town and they are seen as wackjobs...dont believe me? try not to laugh @ this site:

on the flip side if muslim groups protest, oh its serious business! dont clown muslims for fighting and protesting for what they believe in. same thing for jews and gays. I don't get it...why can't christian groups be taken as seriously as other groups?
