It’s pretty easy to set a child’s worldview, since leftist worldview is based on ONE error.
“Man is basically good”.
By extension, “man” is getting better, morally, ethically, and intellectually. From there, you logically progress to “some ‘men’ are more advanced in these areas than others. Just one more small step and you get
“some ‘supermen’ can and should make decisions for the whole of society”.
See how important the biblical view of the nature of man is?
Simply understanding that man is tragically flawed and cannot be trusted with power over other men because of his very nature will blunt the whole leftist worldview.
You are so very very right.
This brief conversation supplied me with a theme for lengthened thought. How sad a truth- if true it were- that Man's age-long endeavor for perfection had served only to render him the mockery of the Evil Principle, from the fatal circumstance of an error at the very root of the matter! The heart- the heart- there was the little yet boundless sphere, wherein existed the original wrong, of which the crime and misery of this outward world were merely types. Purify that inward sphere; and the many shapes of evil that haunt the outward, and which now seem almost our only realities, will turn to shadowy phantoms, and vanish of their own accord. But if we go no deeper than the Intellect, and strive, with merely that feeble instrument, to discern and rectify what is wrong, our whole accomplishment will be a dream; so unsubstantial, that it matters little whether the bonfire, which I have so faithfully described, were what we choose to call a real event, and a flame that would scorch the finger- or only a phosphoric radiance, and a parable of my own brain!--Nathaniel Hawthorne, "Earth's Holocaust", 1844
