Actually not. I have libertarian elements and was a libertarian for over a decade when I was young. I don't dislike libertarians per se.
I just recognized that some libertarian policies are illogical. The biggest being that most of the little people really need a strong government to protect them from powerful corporations and powerful people. No one else will. And even a strong government can only protect them until it is captured by the wealthy and the powerful. I.e. we need more poor congresspeople and senators to protect most of us. Instead we have a bunch of very wealthy people who lack empathy for most of the citizens. As the other poster said-- you are the one who brought libertarians into the conversation and I was responding to your post.
Now on your last point, we may have a strong point of agreement. When you include state and local taxes, the tax system is regressive. We take a much higher rate of state and local taxes from low income people than middle income people and a higher rate on middle income than on high income and a higher rate on high income than on the wealthy.
The details can be found in "Who Pays, a distributional analysis" and it varies by states with some states being more fair than others but on average the poor pay about 10% of their total income in taxes while the upper income pay about 2% and the wealthy typically pay 1% (even less in some states).
When you include social security premiums (which are essentially but not legally a tax), the total tax rate on the low income approaches 40%, on the middle income is a little over 50%, on high income is about 40%, and on the wealthy is about 18%.
Despite this, the wealthy pay most of the taxes.. because they have MOST of the wealth and income.
Why is this so? Because people keep voting for parties who openly say the wealthy is their base and the bottom 50% are all leeches and losers. There are some valid reasons for this-- abortion is a single issue vote for many people. And then you have irrational thinking like the unemployed 59 year old who was railing on talk radio against safety nets when per his own words, he was going to lose everything and be homeless in the next couple months. Why would a person be so against their self interest? Why would a person be so against protection from age discrimination?
I still disagree that it's theft. That's like saying copying copyrighted material is theft. It's not. It's copyright infringement. Electing representatives who pass laws about collecting and distributing taxes to pay for policies and programs they promulgated is not theft.
And, you really need to be more aware of how much government spending really goes to helping the lower income. It's amazingly tiny if you exclude the elderly and military veterans. Spending on the military (of which 10 to 20% goes straight to the wealthy's bottom line) is tremendous and corporate welfare amount to billions or even trillions of dollars (if you include paying for a war to protect the interest of the large oil companies).
You seem very passionate so I take it that you are young. I recommend you go back and study what our budgets are actually spent on and who benefits (it's almost always the top 1% with table scraps dribbling down to the rest). Then think about how a libertarian government is actually supposed to function while assuming worst intent by the powerful. I hope you will see it is in your strong interest to have a strong government to protect you from abuse.
And if you look at the budget figures you will see that social services spending is teeny. With oncoming roboticization and automation, we are going to need a strong safety net (perhaps even a basic income) because we have a paradigm shift coming that will make the luddite thing looks like a drop in a bucket. Even the chinese at current income levels are already being replaced by robots.
