So people get the idea that human nature is depraved, despite the fact that in their own lives there is no supporting evidence for this opinion. I have never seen someone murdered in person
So something doesn’t happen unless you see it with your own eyes? There is some fine libertarian “logic”.
Speaking of logic, perhaps you've heard of the straw man? Alas, if he only had a brain...
Typically I'm more cordial, but I've turned on the flame-thrower for you because you've got an avatar depicting men whose works you've clearly never read, or if you did, did not do so with an earnest desire to understand anything they were talking about.
I did not say that because people don't see something with their own eyes, it never happened. Who the hell would say that? Nobody. So why even pretend that's what I meant unless you're content with being a dishonest hot air balloon with no respect for truth? Your founding fathers are spinning a tunnel to the Earth's core as we speak.
I'm talking about a skewed view of reality. If you never met my wife, and all I do is complain about her constantly for 2 years before you meet her, what are you going to think when the introduction is finally made? You'll think she's a fucking she-devil. If the news keeps cherry-picking murder and mayhem, and entertainment is overflowing with all manner of depravity, and you fill your dome with that all day, every day, you think that's not going to affect your worldview?
Meanwhile, in your own life you may have been mugged once, or had your house robbed, but millions of other people you've come in contact with dealt with you in a reasonably moral fashion. They're not attacking you everywhere you go. There aren't fires in the streets and people throwing bricks through store windows all over the place. Just imagine you lived like Charles Ingles, and never had a TV or radio - how would that affect your ideas about "human nature?"
The poisoning of worldview is a tactic used by dominators to get you to hand over wealth and power to them. There's always some enemy, some danger, that requires you giving them the reigns, at the cost of your dollars, and individual liberty. Just listen to the words of the Stalins, the Hitlers, it's as clear as day. And we think the people who supported those governments were indoctrinated morons, then spout off about the dangers of Muslim extremists, Russians, leftist communists, or whoever, and support our own governmental tyrants, saying they need to spend money this way or that, and make laws about this and that, all the while thinking we're somehow smarter than the rest of the world.
I'm not saying that dangers don't exist, but they don't exist to the degree nearly everyone is walking around believing, and it's NEVER a viable solution to create a seat of immense power and choose some of the worst from amongst the "immoral throng" to sit upon it. And yes, it's proven that sociopaths are drawn to positions of such power, and that they are especially adept at coming across like normal, moral people to dupe everyone into giving them what they want.
They are not public servants. They would gut you for a dollar if they could get away with it. And moreover, external authority is demonstrably and irrefutably invalid and immoral. So, I'm sorry to have to say it, but your OP was just mind-control vomitus on a million and one levels.
Now please reply with the inevitable "TL;DR" and we can go on about our business.
