Democracy. Everyone gets a vote, which leads people to think everyone’s opinion is equal.

Insecurity. People don’t like feeling shit about themselves. It’s easier to find excuses to hate someone you suspect is better than you, than accept the sad truth that you’re less than them. We’re all narcissists to a degree.

A lot of people fluctuate between narcissism and self-loathing.

Vanity. It’s the devil’s favourite sin.
