Kurt Busiek brings forth his liberal bias
Our lesson for today seems to be that expressing conservative opinions is free speech but expressing liberal opinions is bad.

No, the lesson is that some leftists cannot seem to argue or defend their positions without stooping to contempt and vulgarity, as Marz sadly did, while others like Busiek feel they simply must act as apologists. Liberal opinions in and of themselves aren't the problem; it's how the opinionators convey and defend those standings that is. If Marz believed in real etiquette, he would have defended his liberal positions gracefully, and could've even just said "we'll agree to disagree". That would've been the right way to argue on his part. But alas, he did not do that, and instead descended into sleaziness.
I'd say the lesson for today is that some representatives of the comics medium aren't all that different from some people in the movies, which is a shame, because in a time when the comics industry is in such a slump and losing audience, it'd be a lot better if they at least kept some manners, and not turn to apologia for those who've lost their way.
