I agree completely with one caveat:
I would hesitate to include the "uneducated" in there, because, let's face it, EVERYONE is uneducated in any number of things. It is that constant education as we go through life that shapes us.
I get exactly what you are driving at, but there are many uneducated people who don't love those kinds of lies, but instead feel anger and betrayal when they encounter the discovery of truth that can often follow an intentional and manipulative lie.
That said...Lefism DOES prey on the "disaffected" who, in their un-educated" status often bathe in their disaffection, and are ripe for the siren song of Leftism, even when they clearly have evidence of reality.
I have always felt that it is that knowledge of the lie, yet accepting it as truth, is a fundamental reason for the massive level of cognitive dissonance and associated mental pathologies that can be found in the Left.
It was easy to sell their drivel to people like that because you only need to be emotional. It's not important to convey actual facts or to present any ‘substance’.
It's the same now.
I am still stunned at the level of stupidity the NEA has succeeded in passing off as education. I never meet young people who know anything factual or important. They have no capacity for critical thinking and seem proud of their ignorance.
Don't believe it. Just try talking to one of them about any topic. They come out of school as PREY to every idiotic “ism" the Liberals hand them. I worked at a university and even the Grad students were laughably shallow, narrow thinking and the most linguistically maladroit jerks on earth.
