Prager’s dichotomies are crude, and seemingly uninformed. There is much more known about political ideology than the Battle Of Good Versus Evil that he describes.
It certainly is comforting to believe that it’s simply about Us and Them, and that We happen to be on the right political side. But it’s just not a very helpful assumption. It’s overly simple.
Just to illustrate: People know that conservatism isn’t a single thing. There are “traditionalist” conservatives, there are evangelicals, there are libertarians, there are strong-defense global hawks. Each type of conservative may have different things in common with liberals and moderates.
Another issue: Prager misunderstands (or mischaracterizes) liberals. They do not want bigger government. What they want is equality, or at least progress towards equality.
Most liberals would concede that achieving that progress requires more money and more programs and expansion of government. They assume we can afford most of it, or some just think fiscal issues should be secondary. But making government bigger isn’t their goal. They are open to cost-benefit analysis, and they want implementation to be efficient and with impact that is measured. They are not looking for genocide or concentration camps from their government, just less inequality among our citizens.
