Why is our world so messed up? Because 70% of people are sensors and feelers. They have failed in being human because the difference between an animal and a human is abstract thought (neocortex). If I hurt your feelings, that just proves my point in how selfish you are, if you'd rather suppress the truth to avoid criticism.
I don't believe personalities are set in stone. I believe it's only the result of which part of the brain you're using. I can be a temporary ESFJ if I want to. To think otherwise is ridiculous.
