What you perceive is in your head, because your brain perceives. In this case I would say that your perceptions are fvckekced up.
Again, people are in most cases normal. However, political -->regime<--, policies, and training does fvck up perceptions. Most simple example are fags. In some countries fag is a sexual perversion, in other countries fags serve in the miltary, bleed the same, and watch your 6th o'clock. Do you perceive men craving d1ck as normal? Your perceptions depend on policies in place, and public opinion. After all, you do want to fit in. You might think that certain minority of people causes the most crime, but if you call them for what they are, you are racist. Public opinion and policies that shape public opinion do affect your personal thoughts.
Degradation of social values.
