A normality fascist is an individual who is obsessed with his or her narrow definition of normality. In addition, he or she continually pressures others to conform to that rigid standard of normality. This sort of person tends to spread rumors, bully others, and behave in an anal, killjoy manner.
In 1998, Theresa the normality fascist told me that I was too weird to be liked, even though I had never done anything bad to her. She loved to label other things and people "weird" all the time.
