A Caveat must be mentioned: PBS is now funded and its programming perhaps overseen by the Koch Brothers, who are right wing funders of right wing extremism and the Republican Party. Their fortune is in oil and many other things. Still, that does not mean all programming is tainted and it means some programming has worth. BUT one should always know that this right wing slant has taken over what USED to be one of the best public stations on earth and, in my opinion, because of that fact, it no longer is. I no longer give money to support its broadcasting but I will watch certain things I deem have merit.
It is a sad fact and reality of the world in which we live that money buys it all and NOT for humane purposes. It extends far and wide even to the media. Beware and if you give to PBS I suggest you stop and tell them exactly why. The Koch Brothers are major funders of the Tea Baggies, are major deniers of global climate change going against 98% of scientific expertise in the subject. Beware of ALL things bearing their name! --WHY WE MUST ELECT DEMOCRATS IN 2014 AND BEYOND!
