Have I ever, even once, claimed to be an adult? Anyway, blame it on my monkey ancestors.
Seriously, there is a convention in these debates that you don't make assertions that you cannot justify, so you have to be pretty careful about what you claim, or be very ready to back down and apologise (and not place yourself in positions where you have to do that too often). Otherwise you are just making you, and by implication your religion, look shifty and dishonest. I am ready at all times to have any claim that I make shot down in flames, and I'll readily apologise to anyone who can show that I have posted innaccurately. Usually when that happens I've learned something, which is good, and apologising when in the wrong is good for the soul.
