"...except that, whereas conservatives may tend toward the control of things like abortion, pornography, etc, liberalism will end up controlling all the minutia of life -- from seatbelts to what we eat. After all, when the government takes the responsibility for everyone's life from cradle to grave, it ultimately must see the need to micro-manage it all. For instance, if it pays for health care, then it has a vested interest in making sure that nobody participates in health risk. In that vein, liberalism will end up battling within itself AT LEAST as much as it battles conservatism -- because the unintended consequences of governmental care will forever be in conflict with liberal's natural inclinations toward libertine living. :. " - John Hardly

That could be seen as a healthy impetus towards balance, as opposed to a constant bitter struggle, you know.

However, this: "liberal's natural inclinations toward libertine living"...

[Origin: 1350–1400; ME libertyn < L lîbertînus of a freedman (adj.), freedman (n.), equiv. to lîbert(us) freedman (appar. by reanalysis of liber-tâs liberty as libert-âs) + -înus -ine1]

Now you've tossed us a new one. What on earth leads you to the conclusion that liberals are libertines?
