Good comment. I can’t get inside their heads but I note that several leftists I have met have atrocious attitudes and have committed atrocious acts themselves. This seems to translate into having to create a foil (conservative stereotype) that is more evil than they themselves are so their self-esteem isn’t destroyed.
For example, their treatment of children, their hiring of incompetents just so they don’t get criticized in their cushy jobs, the votes they cast for people who do awful things, etc.
I am not a psychiatrist but this theory holds up time and again.
Or did I get that wrong? ;)
