Why do some Christians say that Christianity is not a religion?

i really like the way anonymous lutheran and everyday catholic answered this (though the latter may have been a little bit harsh). christianity is a full-on religion, but fundamentalists will argue otherwise. they will say that christianity is about a relationship with God, and i don't disagree, but i don't think most fundamentalists understand that we believe liturgical worship to be given to us by God Himself. the psalms were intended to be sung. they were given to us by God, and we are to reflect them back to Him as praise. as i said, most american protestants don't understand this. they only see liturgy as a bunch of empty-hearted, memorized lines, and because of their misunderstanding, they dislike it. they view it as a religious practice, and since ''religion'' has become somewhat of a dirty word, they have come up with their own definition of christianity.
