Really we don't need to list those in each party that have said ignorant things. Notice how none of those listed were successful politicians. Arianna Huffington might have start the Huffington Post, but it is a lot of user created content which obviously is going to be pretty horrendous. Bill Maher has quite a few more problems than that, although he is a comedian so I'm not too concerned about his intelligence. It doesn't affect me, I can choose to ignore it.. I can't ignore a sizable number of politicians that choose to make equally terrible mistakes. Unfortunately most (not all) of these politicians happen to be conservative.
Let me clarify, both sides have people that are pretty far out there such as Chopra, in fact most new-agey types are most likely liberal. Both sides also have many very intelligent supporters. What I meant is that liberal politicians aren't representative of the crazy people that support them. There is a large list of conservative politicians that choose to ignore facts, and that is where the problem lies.
Although I wasn't specifically referring to climate change, I would like to address that. According to a paper in the Proceedings of the National Academy of Sciences 97%-98% of the most actively publishing scientists accept global warming. Yes, I got this from wikipedia, but can provide a link to the original source if desired. Those politicians that choose to ignore this are not in any way qualified to make a more education decision than these scientists, yet they base this on a gut feeling. In addition to climate change I could throw in those that are opposed to natural selection. They don't understand the scientific meaning of the word 'theory'. Natural selection is observable in real time. I don't believe there are any anti-vax politicians in Congress (thankfully) although I'm not positive.
I actually really enjoy your posts loggrad, and I'm not trying to argue just for the sake of taking a side. There are quite a number of fiscal policies which I believe conservatives actually have the right idea. I would be willing to vote republican if their position on taxes wasn't to oppose them at all costs. I think fiscally there could definitely be some reasonable compromises, and politicians have been too ideologically attached to their principle on both sides of the aisle; especially lately. Yes the Kyoto Protocol would have hurt us economically. It might not seem like it, especially now, but there are issues out there other than the economy. In my opinion (not fact) it will cost more in the long run to ignore our environmental issues due to famines, droughts, natural disasters, collapse of industries that depend on consistent weather(wine industry), rising food prices, and a number of other things.
I wasn't trying to start an argument, and criticize specific conservatives that are in the media, because like I said both sides have intelligent and misinformed supporters, but I believe that blatant disregard for science is more widely accepted as far as being a conservative politician is concerned.
