I'm not in complete agreement with all the author's points, but I can relate to the "devil's advocate" bit. and I should avoid commenting on articles unless I want to engage the whole article - ya think?I sometimes play devils advocate sincerely to represent a missing part if a discussion.
I have nothing against points being discussed, discounted, explored, or augmented in the search for opinions worth holding. Here's my problem -- some people say, "Let me play d.a." and what they mean is "Let me bring up a whole bunch of arguments that I don't really believe in, just to poke holes in what you're saying and "play" with you - not particularly in the search for opinions worth holding, but to make myself look smarter than you." ... anyway, I'm blathering with generalizations which I hate -- but if it happens again, I will try and remember.
