To be 100% honest with you, a lot of the people I know who've shared it don't really buy it. It's a talking point they like to nod with, but of course it really means (gauging by the their actions at other times): "what I believe is Jesus, but everything else that I don't agree with is merely religion." They have just as strict boundaries as anyone else I know, and it really is just another version of the "in-out" game.
