If we do not party on weekends, our default response is to believe the ones doing so are bad people.

If we do not believe in relationships before marriage, our default response is to believe the ones who have them are bad people. 

We have these moralistic views of what comprises good or bad in people!
Driven by what we do.

Our beliefs make them so!
