Frankly, your last paragraph about "the fandom" really, really pissed me off with it's sweeping generalizations. Who's to say that the narrowness of vision you've encountered is a result of the age of the writer? One of the best fanfics I have ever read in my LIFE was written by an eighteen year old girl. Who was raised in a "strictly religious" household. There's a world of implication in that last paragraph that just really bothers me, because it's all based on stereotypes.
