Now, I'm not taking issue with the fact that someone limits themselves to one genre, I just find the argumentation of "it's made up therefore invalid" quite offensive. Like, on a personal level. I read non-fiction sometimes and I can understand that's someone's favorite genre, but when you say everything is a waste of time because it's made up, you're looking down on people who think it worthwhile. And that's what causes these rants in me.
