I haven't read it in two years and I doubt its any better now, if I see someone eat a turd I would say they are crazy or have bad taste, so that is the same thing, but my post was made in a joking tone anyway.
Reading a comic/manga and eating turd are not the same thing.
Reading is something normal for people to do, regardless of whether or not what they are reading is considered good. It doesn't matter whether or not you have a good mental condition, you can still read whatever you want, because reading is a normal thing among people and absolutely not something that others will find strange. Eating turd, on the other hand, is not something normal and not even good for health, so to say that people who do such things are strange and crazy is normal.
Therefore, for you to have that kind of mindset means you have an extreme way of thinking that may not even be considered normal. Calling people crazy for liking something you do not like shows the kind of person you are.
