There are things that are human constants–We all breathe, we all need to eat, etc. But when it comes to behavior there is no real normal. In my case, I have Asperger’s [or Schizophrenia], so having Asperger’s [Schizophrenia] is “normal” to me; but not to someone else.
Each person has a perception of “Normal” which is based on who they are and what their “Normal” or constant is. When someone comes around that then doesn’t meet that constant they are classified into a category because they don’t meet the “Normal” of the person.
I have different roles, can be either religiously, philosophically, secularly or technically. I view “Philosophical” as abnormal when I am “Religious”. I view “Religious” as abnormal when I am “Technical”. I simply don’t know to which I belong.
