I think that's some very good advice, and I'd like to elaborate a bit. The thing that made me ditch my religion was the fact that I already had a secular, socially liberal, science-friendly worldview, and it clashed with everything they said in church. That conflict drove my de-conversion, and made it easier for me to adjust to atheism. (I was even used to the idea, from most of my favorite authors mentioning that they weren't religious. Harry Harrison, in particular, had explicitly atheistic characters as soon as his publishers would let him.)

So, yeah, subtlety is your friend here.
