There are varying estimates of Ayeshas age. I can give you references from the ancient religious books that can put Ayeshas age around 15. So you can believe what you like to :-). Will muslims love the prophet less ? No. We know about him, we know how he single handedly took us out of ignorance towards light. The political realities of the world will keep on changing. Somtimes x will be in power and sometime y will be in power. But God will remain one and my faith in God will remain one.
