Law enforced by force of arms ended slavery in America, not libertarian BS.
Well I can certainly see that you are a "Force of Arms" type guy.....but you err. This is what finally freed the slaves: We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.
It took a couple of generations....and almost did not even get started until some concessions were made with "slave" states. But, free men cannot tolerate violations of liberty in their midst. Slavery....as a concept, was doomed from the start once we told King George to take a hike! Slavery thrived under Stat-ism.....and a force of arms. Still does!
A free market would regulate and control the usage of dangerous drugs much better than any "gun toting bureaucrat"......or a whole army of them.
