I've been non-religious since before I was Confirmed—yeah, I lied to the priest, and everyone else. It was easier to be an atheist-agnostic on the sly at that point. Besides, by relatives gave me presents.
I tend to see no religion as any sillier than another.
Hitchens was asked in some debate to disprove god or something of the sort. He in reply asked what logical pattern the questioner used to disprove other religions besides their own, and he'd simply follow the same pattern for theirs.
My neighbor up the street was LDS. Nice family, and they were never pushy about it. Kids played together sometimes. Wife still is, but the husband died last year (and they moved). I went to the service, and the thing that struck me was that there was more "sales pitch" for the faith than I'd expect at a funeral. Was kinda creepy.
