This might seem like a crazy episode, but, it points up a difference between liberals and conservatives.
Conservatives are exposed to liberal ideas and commentary constantly. Conservatives are able to engage in debate and discuss of the issues. Conservatives are able to contrast the conservative views with the liberal views, and point out the differences.
But liberals cannot engage in honest debate about policies or positions. Their reaction, when confronted with contrary points of view, is to shut down or shout down the opposition, rather than engage in debate on the issues.
This episode is actually quite enlightening as to how liberals think.
Bit of an assumption, there.
