I can care less about Mary and Joseph, although this is a fabricated story, I've seen this before. You are the one that made the claim, it is you that should provide the prove, otherwise the claim is disregarded. Regardless, if it were true, your point was that Joseph did it so why blame Mohammad; which of course is no defense at all. Sex with children is wrong, now or at any time in history. Furthermore, Mohammad is held to the standard as not only a prophet, but the perfect example for all human kind. Because Mohammad set this example with Aisha, child bride marriages are still occurring in the Middle East, and young girls are dying from this or suffering irreparable physical (and emotional) damage.
Here are a few examples:

Why shouldn't she continue to live out her childhood playing with her girlfriends on swings, playing with dolls (as stated in the hadiths), etc... until she is much, much older and prepared for marriage?

I'm not a fan or follower of any religion, some of them I find worse or much worse than others.If you want to learn how to defend Islam, just know that showing faults in other religions is not a defense for the ills with Islam and the life of Mohammad. That is simply the point I am trying to get across.
