Another common concern is that they all deny reality, one way or another. Socialism will make us happy, taxation will make us prosperous, unionism will make us productive, pacifism will bring peace, disarming will make us secure, diversity is strength, self-esteem is a right, poverty can be outlawed, etc. In these and maybe hundreds of other ways they are characterized by the delusion that wishing for something will make it so. Presumably those at the top of that foul heap are aware that it's all lies, but it's their gravy train. Yet even a few of them are probably fooled.
There's some of that in the Republican party too, but nowhere near as much.
