This is not news anywhere near as much as it is verification:
Not exactly shocking news for those exposed to them for years, but the respected Pew Research Center has determined that political liberals are far less tolerant of opposing views than regular Americans.
No kidding? Do read the column for the full explanation.
Bookworm Room has as the catchphrase on her site, "conservatives deal with facts and reach conclusions; liberals have conclusions and sell them as facts." It is tough indeed to be tolerant of opposing opinions in that instance. My own take on the left is that they seem to have precious little intellectual honesty and their method of rhetoric is invariably to demonize and delegitimize their opponents rather than engage in debate of the relevant issues.
