The leftist is anti-individualistic... He is not the sort of person who has an inner sense of confidence in his own ability to solve his own problems and satisfy his own needs.
A problem is something you can do something about. If you can't do something about it, then it's not a problem, it's a predicament. That means it's something that must be coped with, endured.
We can't expect to solve problems if all we do is tear each other down. You can disagree with a certain policy without demonizing the person who espouses it.
