It was Alan David Doane who did the comparison on his Trouble With Comics blog. He's since taken down the entry.
Yeah, I already figured that out and found a copy of his original remarks. Apparently he was taking a lot of flak from the PC police, as I'm also getting here. I'd say he's a pussy for taking it down, but at least he's not emailing threats of gun violence, I suppose.
Doane's comparing a comic book to covering up child molestation is stupid on its face and breaks down more quickly than most analogies always do. Putting a poor decision made by a commercial artist in the same category as failing to do anything about the serial criminal activity of a sexual predator when one has the power to do so may be a strong indicator of how backwards and hyperbole-prone our Internet culture has become.
On the other hand, Joe Paterno's inaction allowed Jerry Sundusky to commit crimes that only affect a finite number of boys. Once they grow up, go through therapy and get over the horror of having received blowjobs from Sandusky, that problem is done. Joe Kubert actively participated in the perpetration of Before Watchmen, which will now be around forever, always lurking in the shadows to offend an uncountable number of readers into the untold future.
Like I say, I really hate analogies.
