Normal normal, normal is just a word that is based on culture, rationalizations, semantics. It has NOTHING to do with being a balanced individual. All such fetishes originate from somewhere. But our conscious mind blocks it from invading into our "normal" lifes. Yet they still exists. Simply because you attach a word fetish or wrap sth in semantics dependant on a certain culture of that time and place doesnt make such behaviour balanced or the person. Normal only mean it is accepted by that mentality of that society in those times. But those are all parameters dependant on time and place. A balanced human mind is not. A balanced person doesnt need to be dominated or degraded and doesnt matter whether you justify it as a fetish or having fun.
Just because you say its a fetish doesnt change anything. These "personal sexual preferences" are no less a result of a unbalanced individual as if a person would walk around backwards on weekends,quack instead of speak and demand to treat him as a duck.
A human mind is all one thing, simply because our consciousness acts as a sort of inhibition and filter, preventing us from doing stupid sh+t doesnt mean we can diminish its importance and characterize it simply as fetish. Usually these fetish cravings play a huge role in our personality that im certain one could spot little signs if one would engage a person like that in conversation. Lots of times people hide it and act a certain way.
Also, If I wanted to kill anyone that angered me but I didnt, everyone would say im normal, its just rage. No, its not. The same if I wanted to be whipped everyday and it would arouse me etc.. There would be something seriously wrong with me. Matters not really whether I want to hurt someone or not, that only changes whether its accepted culturally or not. But because my mind, self discipline, culture, prison force me to act a certain way, that doesnt change how I feel or what I want to do.
So if someone wants to be degraded and piss+ed on or whatever, that perhaps is a personal preference but that has a root somewhere that made him act that way. Something that shattered his self image at some point , something that made him damaged and now needs to replicate it for whatever reason. I am 100% certain a psychologist would find a lot of heavy baggage with that person specific to that fetish from his past or better yet, he could find it himself in meditation. Yes, we all have baggage, but what matters is how we deal with it, whether we face it and break it or keep the same patterns and go in circles.
