Leftists, by their nature, are weak and given to fits of temper-tantrum when, in the course of life, they are reminded of their weakness and the delusion they've built gets broken.
Leftists lie to themselves as much as they lie to everyone else.
Just the same, they hate their own weakness as much as they hate the strength of others.
Hate is the basis of everything they believe.
Everything they believe makes sense to them because they've experienced enough of life to understand that fallibility of their thoughts.
