Great to be honest. Not always, but mostly I am glad for my particular divergences from the norm and always have been.
The average "normal" person isn't very attuned to the suffering of animals for example, which I always was.
The average "normal" person doesn't question society, life or himself very much (or he doesn't allow himself to question/ has internalized the prohibition to question certain things from his parents/ his teachers), which my parents never set a limit on.
The average "normal" person has a significant optimism bias and has his feet deeply rooted withing delusions about reality and his/ his children's/ his society's/ humanity's importance.
The average "normal" person is perfectly content with his welfare stemming from imperialism, exploitation of humans and animals, with unjust war and subjugation, with slave labour, with animal torture, with imposing serious risk of harm upon the unborn via their conception, with discrimination of all kinds of demographics (the average person used to be all right with slavery, with homophobia and the persecution of homosexuals; the average Germans were totally fine with the holocaust etc).
The average "normal" person living in this world today is most likely a religious nut and seriously believes that there is a man living in the sky, who is his father and watches over him, that hears his prayers (although he never answers in person) and keeps track of the sins of all 8 billion people currently living on this planet individually.
Etc etc
.
The average person living on planet earth today also believes that being gay is a choice, being depressed is a choice, being raped as a woman—"she wanted it"—is a choice and that women should be punished for having been raped.
I can do this all day long.
.
The average parents still think beating their children is good for them and most normal children who were beat up when they were young believe it serves them well.
To sum up, I think love, youth, courage, a clean conscience and the ability to sleep soundly at night are all signs of mental illness :-)
