Indoctrination. Plain old religious indoctrination, from the Official State Religion of Progressivism, that exclusively pounds their religious dogma into hapless pupils for their entire lives.. no exceptions.
They pound the atheistic naturalism belief of common descent, godlessness, moral relativity, constant attacks toward their hated ideological enemies (Christianity), AND the propagandists keep it up for their entire lives of the target dupes.
It is no surprise that so many are deluded by lies and phony narratives about Christianity, given the non stop propaganda they have endured.
As usual, you offer no evidence, just empty claims.
And that is exactly what indoctrination is - repetition of unsupported claims. It is you doing the indoctrinating here - or more correctly, attempting to indoctrinate.
But you're too late. Once one learns critical thinking and how to successfully apply reason to evidence, and learns to think that way as a habit of thought, indoctrination becomes impossible. You have zero chance of reaching anybody here but other faith-based thinkers, who probably agree with you. Are you not aware that others think differently than you do, and simply refuse to believe anything without sufficient evidence?
Incidentally, my opinion of Christianity and Christians doesn't come from any teachings about it from progressive or other sources. It comes from observing it and its effects on Christians and others. I simply observe the Christian bigotries and anti-intellectualism, and its un-American principles such as its incessant theocratic tendency. That's evidence from which one may draw sound conclusions. Nobody needs to tell an experienced critical thinker how to feel about such a religion.
