the old not Democrat = Republican bit again. You can hold two simple concepts in your brain. Once you exhausted "Democrat" there was only room for one more, which you label "Republican." Actually I'm a libertarian, but if "Republican" is all you can grasp for anyone who thinks differently than you, then I'm indifferent to the label other than I think it shows how clueless you are. But as to your point.
So you want to count corporate taxes, estate taxes, investment taxes that the rich also pay far more of than the rest as well? You have me there, only counting income taxes under counts the amount the rich pay, doesn't it Keith?
If you are a libertarian, you have to be brain damaged. Because, as a libertarian, you are backing an economic theory with no actual history in fact. Look, libertarians are simply far, far right republicans. You know, republicans who are ok with drugs and want to get laid. But, me boy, most libertarians give it up before they reach puberty.
So, of course, you can not discuss anything with a libertarian. Because they are delusional. Unable to see that their economic theory has not and will not work in the real world, libertarians simply argue a concept that they have been sold. And learn that, for them, truth is what they want to believe. And they find their "truth" in their favorite bat shit crazy con web sites. And learn to hate. Because they love hate. And believe what they want to believe. So much easier than actually having to do the hard work. Like study. Like seeing both sides. Like research. Like vetting statements for truth.
It is just so simple to be a libertarian. Just believe what you are told.
But then, it is entertaining. And rather comical.
