So you see, like socialists, and unlike either democrats or republicans, libertarians base their ideas, not on pragmatism, but on actual ideas about right and wrong. Politics are subservient to ethics.
Ah, but you are implicitly asserting that your ethics are superior to mine. What if we disagree on what the ideal good is? In a society of 300 million, that is going to be inevitable. We can't resort to what works best for most of the people most of the time, i.e. pragmatism, because you have rejected that as a valid basis for a social structure. You state that it is evil to force anyone to do anything they don't want to do, as though that is some hotly debated principle. It's not. Most people even accept the corollary, that it is also wrong to prevent anyone from doing that which they want, with the caveat that their actions have no negative impact on others. Which is again where we run into the problem of basing our society on ethics. Take 300 million definitions of harm, with no allowances made for pragmatism, then try to build a society that minimizes that harm. Good luck.
