Well, think about any other symbolic gesture of religion that can be thrust upon someone before they've developed the cognition to say "wow, this makes no bloody sense". If we can avoid getting into a circumcision argument (which has already been done to death in other threads), the question is more "which symbols are important?" If I was raised as a Hasidic Jew, and grew my beard out as a result, were I to renounce my faith, I'd be likely to shave the beard off. I wouldn't wear a yarmulke anymore, either. Asking to be unbaptized is equivalent to removing any other symbol of a religion from your consciousness. It's a washing clean (as it were) the religion from oneself.

By asking to be unbaptised, they are acknowledging at least the religion has some truth. Enough to be frightened enough to go through an (to them) a ritcual to remove a ritcual that has no power (again to them). Isn't that being hoisted by their own Pitard?
Petard, first. Second, no. In the same way your desire not to wear a yarmulke or celebrate passover doesn't indicate an acknowledgment that Judaism is somewhat true, removing the vestiges of another religion you don't believe in isn't indicating a "fear" of a ritual. If you converted from Islam to Christianity, you likely wouldn't pray five times a day to Allah. That's not fear of the ritual, that's a belief that it's irrelevant (if not flat out wrong). The symbol has a meaning, just not a theistic one. It's a symbol of a corrupt, ignorant, and destructive institution, and I can understand why anyone would want to make as public a declaration as possible that they want nothing to do with it.
On the census data stuff, it's true in America as well. Often, atheism is counted by subtracting the number of people on the rolls of religious institutions from the total population. If you've been baptized, you're on the rolls.
