I’ve had a few recently interesting debates with my usually leftist friends (after a few drinks of course, at parties). Typically, I tend to abstain from debates (offline) when they enter the realm of economics, since even though I understand enough to object, especially when they start spouting intervention nostalgia for the great depression, I don’t know enough intracate exmaples to make effective counters without digging myself into an argumentive hole.
However, the recent arguments have been more theoretical, and I’ve made quite the impression on them concerning post-statism, and I think they were quite receptive when I gave them my theory on how Marx may have been right on capitalism being a stepping-stone for another system, but wrong on it being Socialism. I essentially said superconductive capitalism in the vein of open-source movements, which, luckily, a few Linux fans there grabbed onto to let me finish.
But yes, I would say that was my favorite so far since I felt like I actually got some friends of mine to think differently, if only possibly in a passing manner.
Of course, we also had some crust-punks there do their usual anarchism spiel, but I sadly couldn’t take them seriously when I was attacked for mentioning that I read Ayn Rand on ocassion (not even books, yet; mainly excerpts & the wikipedia entries); so much for being open-minded. Oh well, offline debate is a hit & miss sometimes.
Other than that, I actually found some good arguments at Libertypapers; one in mind was an argument against someone who went by the handle “jim”, at this comment page (I also dipped my toe in the argument, but essentially was just fanning the flames of argument against his logic): http://www.thelibertypapers.org/2008/03/27/why-mike-gravel-is-not-a-libertarian/#comments. It ended with a post to the abridged, illustrated version of “Road To Serfdom”, which I thought was a bit funny, as well as nice preview for when I actually get to reading it myself…
And of course, Mises always offers good debates & conversations. I usually end up reading more of the forums than I do recommended reading, at least, for now :D.
