I think a man desiring a young girl is called pedophilia only if acted upon. I see it’s very common in memes, Japanese anime, and so on… FBI open up. And I think a young girl, at least at 13, desires marriage too. I don’t see an issue with the marriage except when modern customs and traditions are imposed on it. But in principle I see no problem with Muhammad’s marriage as long as it was accepted socially, since it was basically imposed and tribal circumstances allowed it.
