"When people have their identities completely wrapped up in a belief system"
Just out of curiosity, do you think so little of us to assume that our beliefs aren't held because someone told us so, etc, and we aren't capable of coming to those beliefs on our own?
Have you considered that we've weighed and measured all of the alternatives, gave them time, thought and consideration, and chose to believe they are wrong?
Or is it just easier to assume we're a bunch of lemmings?
If the latter, why do you associate with people here?
