"Forming an opinion on each issue on its merits, rather than defining yourself as liberal or conservative and then adhering to the liberal or conservative position on each issue, without really thinking about it, appears to be the one unforgivable sin in political thought."

Ah, I see. So that means defining people with statements like "folkies being, for the most part, knee-jerk liberals"
is a well thought-out and considered position, is it? Hmmm...interesting.
