Well, it's quite complicated. In order to truly understand, one must be well-studied in critical theory. An expensive liberal arts education would help.
But, to try to reduce it to the "layman": my carefully crafted logic works like this:
I don't like anime, usually.
To put that in the form of a logical hypothesis:
1. I like good things.
2. The things I like are good.
3. I don't like anime.
4. Therefore, anime is not good.
