Liberals are hopelessly stupid, shaped by the media around them, and only understand things in terms of good guys vs the big evil villain. The propaganda machine very well abuses this fact, while these low intelligence liberals are incapable of seeing the problem with it since they are incapable of thinking in any other way.
They form their identities in their stupidity. It hurts them both foundationally and materially to accept that they're wrong, since they have formed their relationships with their communities based on the product mutual stupidity. For them to change would be a violent upturn, much like a person born and raised in a religious cult having a sudden fallout from said cult. It can entail ostracism, loss of peers, loss of shelter... Others are like priests that get to fancy themselves leaders and abuse their concubines, motivated to believe their own lies where they're otherwise worthless.
Think of how many liberals have family members in the military or are military members themselves-- much like the nazis, they convince themselves they are good guys to persist. Think of how many people's only hopes are to somehow 'make it' in a liberal economy, especially when they have dependents? How many people are just uglier, less intelligent (as liberals tend to be), talentless... and their way of signaling value is capital, either by relentlessly chasing it or at least being committed to it, like a dumb and ugly person that gravitates towards faithful piety and commitment to Yahweh or something.
Liberals are anti-intellectual cowards as a survival mechanism, much like a person dependent on welfare most often cannot afford to go up in the tax bracket.
Liberals live an embarrassing and wholly undignified existence, and the best thing you can do to them is scam them and give to communities that need more. They will violently stand against revolution and progress, and as such deserve all the violence and terror they often invite.
