Ordinarily, I wouldn't post the nearly contentless "Agreed," but since the opposing point was made in reply to my post, I thought I should say something to show that I read and was moved by roc's point.
Any recommendations for what I should have done instead?
You did the right thing. And at least you didn't commit the heinous sin of applauding. I spit on clappers, curse their mothers, and I make a strong point of never breathing their exhaled air.
