And to them, fantasy books would be garbage. I, like many other people, know what I like and can judge fairly accurately when something is not my cup of tea. I do not need to read any of Fifty Shades of Grey to know that I would not like it. I would even argue that there are indirect means by which I could label it as mere-wish-fulfillment-escapist drivel, but that's another conversation all together.
In other words, there are plenty of books I would like to read and I need to make judgement calls on what to not waste my time on. When I read drivel, I want it to be drivel I enjoy, and I'm pretty good at this point in knowing what I like and what will enhance my life.
