Good observations. The English language is a treasure when used competently and precisely.
I would replace his “the ugly truth about human nature” with “the current tempered realities of human capacities”. Likely there is a more poetic way of getting the point across.
But his broad outline is good and serves as a template for developing his observational summaries further.
What grates my daily thinking about liberals is their simpleminded notion that they alone see the ideal destination for humankind. For example, they see environmental degradation and in response organize politics to punish the abusers and and push upon all myriad fantasy solutions which sound good but are not tested and not practical. And the part that is so infuriating is felt when there exist true innovators who work to take the painstaking practical steps towards real solutions and this progress is usurped by liberals who claim that such progress would have never existed if it were not for their organizing the politics surrounding it.
In short, liberals see something that is universally wrong and they jump up and down like children pointing to that something which is wrong as if they are the only ones that see it. Then when a more adult group notices that thing which is wrong and takes steps to right that wrong, liberals take credit in saying that without their pointing out the wrong there would never have been a solution. Therefore, it was they that solved the problem.

Agreed, and your further observations are "spot on."
