I personally think it's ridiculous to label Mohammed as paedophile and use it as an excuse to criticize Islam - Everyone back them married pre-pubescent girls, Europeans did it too for some time and Queens could procreate since the first time they had period. I'm not saying that it's right by today's standards, but it isn't a valid criticism of Mohammed.
