Probably no more delighted than you would be if one of your kids told you to stop pestering with that religion stuff because they wanted to become atheists.

Actually I'd wonder which adult had been evangelising in their general direction. If it turned out it was a free choice based on spontaneous interest from books/reading/TV and not on unsolicited pressure from an adult, I'd be perplexed but supportive - which is not, I suspect, what you would be.

In practice the difference is that most churches baptise children before they can have any possible idea what the symbolism of baptism means, and also before they have any possible way of expressing dissent.

Obviously it's nonsensical to claim that's an expression of free choice for the kids, for reasons that are surely obvious.

May God preserve the sense of superiority of all atheists!

Enough with the weasel words, insinuations, and victim plays already.

Your 'freedom of religion' clearly extends only as far as the 'rights' of the religious to evangelise their beliefs.

When confronted with the possibility of actual freedom of belief you're dead set against it.
