As a "silly superstitious" theist, I can say I've never done such a thing. Not even as a christian (I felt I wasn't "saved", so I couldn't remove the mote, etc.). I don't fear hell, I am most certainly not christian, and I discuss my beliefs only when asked (and sometimes not then!). And I never talk about them in the sense of "well, I know X, and you should believe in X because Y." I find it all rude and silly, and my beliefs don't have a "grand commission" attached.
I am most certainly an Ex-C. Just not an atheist.
