Early last week, Rush Limbaugh said something I never thought I’d hear him say on his program: nothing. I thought my radio had broken. When scrambling to find a legitimate reason for his absence at last week’s Tea Party rally on Capitol Hill to protest the forthcoming — and now passed — House health care bill, Limbaugh fell silent, absent for “scheduling conflicts.”

But despite not physically being on air, his presence was felt at the Guy Fawkes Day rally — via at least one protester, who thought it would be a wise idea to brandish a large, graphic photograph of the victims of the Dachau Nazi concentration camp. The attempted message was that President Obama’s proposed health care reforms bear similarities to policies advanced in Nazi Germany.

Unfortunately, it wasn’t a real surprise that imagery of this kind reared its head on Thursday. Throughout the summer months, Limbaugh shamelessly attempted — and, clearly, largely succeeded — to convince his listeners that Obama’s “socialist” policies were eerily similar to the domestic policies of the Nazi party. He even went as far as to, on air, make a more direct comparison, declaring that “Adolf Hitler, like Barack Obama, also ruled by dictate.”

There is no way to defend this rhetoric, unless one actually does believe Obama is bent on mass murder. Whether Limbaugh and the others who support and have helped push this meme merely want to compare Obama’s governing style to the aspects of Nazi policy that had nothing to do with the genocidal extermination of millions is irrelevant. Regardless, the message and its implications are offensive — and, above all, dangerous.

Thursday’s incident was so public that it was impossible to ignore. Republican House Whip Eric Cantor quickly condemned it — and Limbaugh, by implication — by telling a reporter, “Do I condone the mention of Hitler in any discussion about politics? ... No, I don’t, because obviously that is something that conjures up images that frankly are not, I think, very helpful.” However, this reaction is only coming after this most recent manifestation of health-care-reform-is-Nazism thought; where was Cantor over the summer, when he could have joined many others who have been expressing rightful anger against such rhetoric?

When I first heard these comparisons being used over the summer, I believed that rational thought would eventually win out. The comparisons are completely illogical on so many different levels that it’s frustrating that it even needs to be discussed. This initial sense of optimism, however, was no match for Limbaugh’s army of ditto-heads, who made it clear when they called into Limbaugh’s show that they honestly believed that Obama and Hitler have the same basic ideological principles.

These comparisons are so off the wall that one could also be forgiven for wanting to ignore them. However, the messenger makes this an imprudent course of action. Limbaugh and his closest acolytes have created a niche for themselves within the public discourse in which they are seen by millions as legitimate, well-respected political thinkers. When Limbaugh voices these views, even tentatively, they’re imbued with a very real legitimacy. The impact is roughly the same when he listens silently or with tacit approval when a caller makes a similar point.

Ultimately, it’s the messenger who pushes such rhetoric beyond merely crassness and offensiveness and into territory that is genuinely dangerous. Limbaugh constantly brags about his legions of followers; yet it only takes one demented soul to buy into the argument to wreak horror on the nation. After all, given how unspeakably horrifying Nazism actually was, how far might someone feel he has to go if he believes Obama is Hitler reincarnate?

We’re only months removed from the murder of Kansas physician George Tiller, demonized by the likes of Bill O’Reilly for his willingness to perform late-term abortions. Scott Roeder, who murdered Tiller, echoed the sentiments expressed by conservative talkers in remarks remembered by acquaintances; it’s not far-fetched at all to be concerned over whether comments by men such as Limbaugh to the effect that Obama is pursuing Nazi-like goals could inspire a similar reaction.

Nothing can excuse the aforementioned scene at Thursday’s rally, or the other scenes just like it in which protesters compared Obama to other dictators or real villains of history. Additionally, previous scenes comparing George W. Bush and former Israeli Prime Minister Ariel Sharon should have been equally condemned. It doesn’t matter what your political persuasion is, the message should be censored. Using the Holocaust as a basis for an argument against any domestic policy — unless that policy is literally one that calls for the subjugation and destruction of an entire segment of society — demeans the historical tragedy and the experiences of those who had to bear such a torturous hell on earth. Finally, while these arguments are hyperbolic to the extent that they will never be taken seriously by the serious-minded, what of everyone else?

At a town hall event held over the summer by Massachusetts Congressman Barney Frank, the Financial Services Committee chairman stopped a similar protester in her tracks by pointing out her poster comparing Obama to Hitler and explaining that having a conversation with her would be akin to trying to debate a dining room table. And it was comforting to see such hate make no progress in a respectable forum.

However, such discourse is still treated as if it’s pertinent from 12 to three in the afternoon every day on the Excellence In Broadcasting Network. If such talk is tolerated there, then how can it be stopped from seeping into the rest of nation’s political bloodstream?
