Most of you have probably moved on, as I have, from the vain attempts to introduce the Libertardians to the benefits of facts and reasoning in making more intelligent arguments regarding drugs and legalization. I haven't done double-blind testing, but I'm also 99% sure that Ayn Rand is the gateway drug to stupidity. (But I digress.)
But after six attempts with nominally the same commenter, and running the gamut of dealing with nearly every entry in The Dictionary Of Logical Fallacies, and pages of responses, it's time to point and laugh. Or at least get a post out of it.

If not, move along; nothing much to see there.

Win any argument with this one weird trick: use facts and evidence in support of the proposition!
Go over there and take notes. If only to stop shooting yourself in both feet.
