And like Tam says, there's no sense throwing away good material at an away game. Besides, this is important.
So Miguel posted up this article, and a good discussion was had in the comments...
...which led me to seek out and find this article from January at the Volokh Conspiracy.
It's worth looking at because it gives a unique glimpse into the Leftist/"Progressive"/Collectivist mind. As it happens, conservatives and libertarians (both big 'L' and small 'l' varieties) -- hereafter referred to as "The Right" -- really do resolve moral dilemmas differently from Leftists. Psychologist Jonathan Haidt identified five (or six) "vectors of morality" people use to decide the "correct" position, and noted that while the Right tends to weigh all five (or six) more-or-less equally, the Left places value in only two, essentially ignoring the rest.
Perhaps most interestingly (and perhaps as a direct result), while the Left is unable to accurately determine or predict what the Right thinks and does, the Right has no trouble at all figuring out the Left's positions.
Where the Left can seem to justify anything based on their values, the Right can only "universally" justify a few things and seems confused or conflicted on others. According to Haidt, this happens when the five (or six) factors conflict. The Left, using only two factors -- the most highly subjective two at that, in my opinion -- rarely experiences this dilemma. On the other hand, where all the values align and agree, the Right has a much stronger moral position and a "thicker", more layered justification for holding that position.
I believe this is also why the Left relies so heavily on straw-man arguments, projection, and other logical fallacies; they really don't understand the conservative mind or value system, so they have to fill in the gaps somehow. Their conclusions are technically logically sound, but their initial assumptions are way off-base. Garbage in, garbage out, as it were.
The take-away is this: We really can't reason with the Left on issues of right/wrong; their moral compasses are calibrated to a different value of North.
Just thought I would share. Enjoy!
