I'm trying the Add This! application on the blog. Last time I tried using this sort of thing, it slowed down the site's loading speed ridiculously, and if it happens again, I'll take it down.
Side note: if you want a real world example of the person who thinks he's morally upright but who is rationalizing something odious, check out the debate on torture going on between Patterico and the posters at Obsidian Wings as well as over at Balloon Juice. Patterico obviously thinks that he's created a situation where torture is morally acceptable, and refuses to acknowledge that he might be wrong on this.
