Your response is thought provoking; however, you lose a bit of credibility because of your tagline.
You seem to have accepted the conventional wisdom that "liberal" in itself is destructive, when it is merely liberal, and there are degrees of liberality which a quite at home in any reasonable discourse; however, the left has crossed the line into "mental disorder," yet you seem to ascribe that to liberals.
In the same way you claim that Stalin invented the association between the right and fascism, the left has created the association between itself and "liberals," many of whom are pretty good folks, not the militant deconstructionists of our time who conservatives too often call "liberals."
Liberalism - as in today’s far leftism, which has nothing at all to do with classical liberalism. Or even the Dem party of 40 years ago. Just look at how the Far Left threw Lieberman under the bus - though I disagree with most of Lieberman’s positions, I give him credit for breaking the mindless lockstep on at least a few areas.
BTW, I have some friends who I consider “old school” Democrats, who do not like the direction that party has gone and have been voting at times Republican (however I have concerns about the Republicans and their sometimes pandering to the far left, even though I am registered as “R”). Disclosure statement - in my younger days I was a Dem, but more of a Henry Jackson Dem than the George McGovern variety.
