This is entirely accurate. It was some lone asshole on /v/ whose retarded gimmick ballooned out of control.
I don't hate any "moral" characters (read: moral absolutists), nor do I root for the "good" guy without condition. I'll cheer for any character I find more clever, or at least more entertaining, than their opposing number. Case in point: Suzaku's not much smarter than Lelouch (they're both stupid characters in a stupid show), but I root for him because he's got more of that cheesy Justice-League motif going for him with the token HARDCORE EMO EDGE that fails to offset his spin-kicking Japanese-Superman hilarity value.
In a different instance, I found Light entertaining because of his thorough self-absorption and immense hubris, which was a refreshing change from most shonen-manga protagonists. But I still rooted for Near, simply because I liked his cold-blooded style and grizzled-police-chief contrast to Mello's cop-on-the-edge approach to Kira-hunting. "Dammit Kihael, I want your badge and your gun on my desk by sundown!" That, and it was just way too fun to see Light laid low and squealing like a spanked child after thinking he could get away with such immense gaffes and laziness after taking out L.
But my favorite "moralfags" are the ones without pretension -- the ones who act out of that berserker bombast and self-assured fatalism that we've lost in our postmodern soul-searching. Characters like Luffy and Joseph, who are dumb as rocks but know good and evil when they see it, charging boldly into dangerous situations and beating their opponents as much with wit as with their bullshit manga powers -- those are my favorite moralfags.
