Perhaps I am misunderstanding this idea.
But what I see in society is that each side of the political aisle believes that what they are doing is moral and serving humanity in the long run.
Take health care, for example. The Left believes we have a moral duty to provide affordable health care to all people, and that people of wealth should be taxed at higher rates to pay for it. Conservatives, on the other hand, believe that health care is a service that is provided at a level that each person is able to afford.
In the larger picture, conservatives believe a government that provides for the well-being of its citizens discourages good character traits like discipline, savings, and personal investment. While from the liberal view, government programs give the citizen the freedom and possibility of self-improvement and pursuing happiness.
I think my ability to have friendships with liberals, and I have many such friendships, is my belief that they mean well and have good intentions (for the most part), but that their methods ultimately do more harm than good.
Progressives, though are a different story. They are elitist and their only goal is dominance, power, and superiority.
It's just that the one side rejects God's way of doing things and inserts its own twisted morality, doing things to “help” in the short run that, in the longer run, ruin the very thing they were trying to fix.
