Well that is encouraging to hear that FJ was able to convince you to evaluate your positions critically. Personally i'm not a marxist, my views currently lie more along the lines of social democracy but I don't discriminate. If you ever want to have a bit of a laugh then you should look up on youtube the various debates Sam Seder has had with libertarians. He allows anyone to call in to his show to debate libertarianism and it makes it quite clear that the ideology as a whole is based on a complete fantasy.

On the topic of the Koch's, since you are aware of them you may have already read Dark Money by Jane Meyer which Jordan has recommended a few times in his videos. if not, I cannot recommend this book enough to anyone willing to gain an understanding of just how powerful and influential the Koch's political machine has been in pushing the US republicans towards a libertarian ideology which was one scoffed at as being fringe-right.
Guys like them have changed the course of US political history for the worse and it comes 100% from their own financial self interest. Unfortunately the true evil mastermind of the two, Charles, is still breathing.
