Non pagans have an attitude of "This is a fun tradition but noone actually believes in it" while pagans can tend to be smug about how their religion doesn't have all the offensive wars and oppression that are "the only reason" people object to religion ie christianity. Both attitudes (while somewhat contradictory, and I'm sure the former irritates the heck out of pagans) give paganism this vibe of friendly inclusive harmlessness.

Hmm. This is exactly why, as a Christian, I like secularization: it serves to divorce the rich rituals of tradition from any specific set of beliefs (and, from my perspective, make room for genuine faith and a chance for the Holy Spirit to work). If only secularization wasn't so Christocentric, but could draw upon various religions more equally....
