How's your BS detector?

If you would like a refresher in basic logic—say, for the sake of dealing with all the distortions and untruths floating around in the political arena these days—then you may find a lovely summary by Liberal Jarhead at Bring it On! I highly recommend it.

Here is one of Jarhead's introductory paragraphs:

There’s nothing wrong with disagreement, and a good debate leaves everyone involved better off for having had to consider other points of view and reassess their own. But for that to be true, the disagreement has to make sense. What I’m talking about here has nothing to do with honest, reasonable debate and everything to do with substituting ugly emotions and closed-mindedness for thought and real argument.
