There are population segments of my country whose dogged traditionalist beliefs fly so strongly in the face of reality that it holds back the rest of the country so very dramatically that it brings about an irrational urge to see whole American communities purged with fire.
This isn't the 1950s anymore. There are now twice the people on the planet than there was then. We no longer live in a world of plenty, where opulent, self-indulgent ignorance can operate. It's this uncomfortable reality that they refuse to accept, and we all - the whole world - suffer for it.
What's worse, the Republican party has largely been infiltrated by borderline criminals - they no longer represent anyone's interests but the extreme upper class, and they stay in power by lying their asses off, as they have been in the matter of Universal Health Care. For example, death panels are a complete fabrication. Another example: astroturfing. These actions are really leave little room for doubt: the corruption of the party is absolute.
The more intelligent Republican voter knows this, that's why they voted Democrat in 2008, and will hopefully continue to vote Democrat until they successfully root the corruption out of their own party.
