Third you should debate with atheists the same way you should debate with anyone else -- with respect, honesty, integrity, and offer rational arguments supported by evidence rather than just opinion.
He's not writing generally about "how to debate", but specifically: "How to win religious debates against atheists' typical arguments".
Some of the stuff he says is decent advice, but it seems to all boil down to being motivated by proselytizing.
So for me, its pretty pointless. My thought was: "who the hell cares? Why should "winning" against atheists be anything I care about?" And then I realized: Oh yeah, I'm not evangelical.
