I've never really read much fanfiction, rather I've largely avoided like the plague due to some rather uncanny recountings about it from friends. Still, that didn't stop me from writing a lot of it back in the day when I was younger. I wrote furry Minecraft fanfiction, your argument is invalid. I don't do it much anymore and when I do it's usually as a joke for friends and it never goes beyond a small circle of friends.
