Time to get back to laughing at superstition.

Well, in all the hysteria and ill-feeling surrounding Atheism Plus, I've grown almost nostalgic for the sort of stick I usually only get from religious people.  When you've grown accustomed to "you're a murdering whore and you'll burn in hell", "gender traitor" and "chill girl" (which latter I rather like, actually) can only ward off the cravings for so long... and I'm jonesing for a meaningful argument now.

So, I thought I'd ask everyone - here and my lovely peeps on Twitter - a question.  Well, two, actually, though they're related.

1: What's the single dumbest/silliest/wrongest/funniest/most infuriating argument you hear from believers in defence of their faith, and why? (And if you'd like to explain how it's wrong, please do so of course!)

2: If you could wave a magic wand and make every religious/superstitious person in the world understand just ONE thing, what would it be and why?

I think it'll be interesting to see how many of us hear the same arguments, which ones annoy us most and which are most common.  We all have slightly - in some cases even widely - different reasons for opposing religion, it's always fascinating to hear how other people think about things.

Please let me know what you think!
