I agree with most of your post.
However, the fact is that people like you and me, don’t want to be “Told” what to think or believe. People need to discover those truths for themselves.
Any form of government that insists on enforcing a belief system will encounter rebellion.
To equate Libertarianism to moral relativism is a mistake on the surface.
The difference being the governments ability to force moral relativism on the populace, which is what we have now, and the people having the ability and freedom to figure things out on their own.
Yes, it is “Non-interference”, but it is not moral relativism.
It is peer pressure without redress.
It is a leap of faith. This is what liberals and progressives can’t handle. They don’t trust their fellow man, primarily because they don’t trust themselves.
You understand. And when non-trusting (fearful), control minded people encounter something they don't care for, they ban it and to hell with the consequences.
Thus, we have tried to ban guns, alcohol, every drug, including and now especially cigarettes, sex, riding without a helmet or driving without a seatbelt and to what end?
Certainly not liberty. Not when the answer is because those "things" are misused by a minority of those who do use them, NO ONE can have them or the freedom to decide for themselves and accept the consequences.
But...Human nature must be controlled by those who know best, so we must take those toys away, while exaggerating their danger as justification for the good of all. Right?
“Do you think that we want those laws to be observed? We want them broken.
There’s no way to rule innocent men. The only power the government has is the power to crack down on criminals. Well, when there aren’t enough criminals one makes them.
One declares so many things to be a crime that it becomes impossible for men to live without breaking laws.”
– Ayn Rand, Atlas Shrugged, 1957
"Political tags - such as royalist, communist, democrat, populist, fascist, liberal, conservative, and so forth - are never basic criteria.
The human race divides politically into those who want people to be controlled and those who have no such desire."
