I have come across a lot’s of people like these. like 99% of them. Sometimes it makes me think twice if what i am saying is wrong? What’s wrong with them. Is it so hard to swallow your pride and acknowledge that the other person is speaking facts? When they come to know they are wrong they proceed to insult/make fun of others to save their ass. Just why?
Cognitive dissonance. People see themselves as rational and intelligent and anything that counters that is very difficult to accept, so they double down.
