I have thrown my lot in with Republicans because I believe they are the only viable power to stave off the socialism and moral degeneracy of the Democrats.
But I am an bred-in-the-bone American and raised Christian, and these are nonnegotiable items with me.
Libertarians have the right to their view of the world and to place their loyalties where they want. I disagree with them vehemently about elevating the legalizing of drugs and moral permissiveness to a "principle," but I do not expect them to vote for my candidates. If they decide to, that is their choice. If they don't, they can suffer the consequences of their choice, but they may feel they will suffer less emotionally/intellectually if they stood up for what they believe.
What I does bother me is people who call themselves, not Libertarians, but "conservatives" and wrap themselves in the Constitution and then stand by and let liberal/socialist/SecondAmendment haters/anti-Americans win elections because the Republican candidate was not pure enough for them. And the conservative purists say they are fighting for the founding fathers' vision of America. That does bug me because I think their tactics are counterproductive.
But Libertarians are not fighting for the founders' America, they are fighting for some other vision of what they want America to change into, which is their right.
Here's the thing though... Libertarians want YOU to make those moral decisions in your life. History is litered with examples of societies who have fallen into decay and despotism AFTER they enacted goverments that tried to enforce some morality by government edict. This just plain doesn't work. It removes the consequences of a persons actions and negates any need for a person to formulate morals on their own. That's the short answer.
Would you really want someone like Bill Clinton using force of government to enact his "moral" code on the rest of us?
It's not that we feel having loose morals is a good thing. None of us see drug abuse as a good thing. What has spurred us to action is the fact that those in government have done far worse to whipe out some percieved "moral" bad. The ends does not justify the means if your "cure" is worse than the disease.
Who would you rather have making those moral decisions in your life? Yourself, or Hillary? Libertarians want you to make them and to live with the consequences of your actions. Hillary, and her ilk, think they know better than you.
