Now that everyone's gone suitably self-righteous over Tom Coughlin's joke about how online, he's hated almost as much as Hitler, I'd like to offer a humble proposal for an alternate analysis.
While it's all well and good to read what Coughlin said as some kind of catastrophe, ("Does he think he's Hitler? Is he joking about how much he's hated? Is he that thin-skinned? Is he asking for sympathy? Aaaaaghhh!"), but I'd suggest two things. One, Tom Coughlin can't tell a joke to save his life. He's like the outtakes from the Lorne Greene Comedy Hour - the bad ones. And make no mistake, he was trying to tell a joke.
Two, he was not comparing himself to Hitler. He was not considering himself a martyr. He was not doing anything other than attempting to make a wry comment on how absolutely berserk the online commentary about Giants football (consider, for example, this image over at Off Season On Smash) can get.
Besides, anyone who spends any time online knows that as soon as you mention Hitler in an argument, it's automatically pointless from that point on. Would that the talking heads of sports radio could learn the same.
