Lyric discussion by ExNihilo17 

Cover art for Bon Idée lyrics by Regina Spektor

I don't think it has to do with being ridiculed for one's ideas, because

these lines: "Don’t tell your gods you no longer believe Because as soon as you say it out loud they will leave you"

I find the lines to be true. I'm an atheist, and I've been one for about 5 going on 6 years. And it wasn't until about three years ago when in an off-hand remark gave it as a reason to my friend for not going to church that I actually believed it and felt it.

Anyhow, I agree with sairecafe's interpretation.
