Harry Potter fanfic patterns

I've noticed that when religion is introduced into HP fanfic, almost always the author is male. I've also noticed that whenever I read a fic that has religion, it also has a rather bizarre sense of machismo. Of course, I have read male authors that don't use religion and I have read machismo that doesn't use religion, but when there is religion I'd say 95% of the time you're going to have a male author and a macho Harry.
