Slashdot keeps giving me mod points, but I almost never get to use them up because there's no -1 Stupid option. -1 False Dichotomy. -1 Denying the Antecedent. -1 Slippery Slope. -1 Straw Man. -1 Tu Quoque. (Though I'm often tempted to list all Ad Hominem as -1 Trolls.)
And, of course, -1 Wrong. If it's honest idiocy, -1 Troll is wrong, and of course replying to correct it is good, but even if it's already been replied to, it still should be ranked lower for being wrong. -1 Overrated? I guess.
I find I reply more often when I have mod points.
