Some conservatives that I talk to on the internet tell me that conservatives used to be sane but are now becoming increasingly insane. I agree.
"Deport all liberals."
"Liberals hate America, they hate flag-wavers, they hate abortion opponents, they hate all religions except Islam, post 9/11. Even Islamic terrorists don't hate America like liberals do."
Democracy comes from the values of The Enlightenment. The philosophers of the enlightenment loved to question things and discuss things - that is why they created modern democracy. The political arena is now full of people who do very little questioning and are totally cocksure of themselves.
I don't think that we will still have representative democracy in 40 years. I don't think that representative democracy can survive in an environment with so many cocksure people. Someday the majority of the political people will just come out as opponents of voting.
