Limbaugh: Just Kidding

Conservative radio talk show host Rush Limbaugh recently dismissed President Obama's "green energy" program as a mirage based on non-existent solar and wind industries. Limbaugh's claim would certainly be news to those participating in the well documented explosive renewable energy growth occurring in the global marketplace.

If anyone could ever publicly corner Limbaugh and confront him with numbers clearly disproving his absurd contention, you can bet on a very predictable response to avert embarrassment. When somehow forced into a corner for gross on-air excesses, Limbaugh over the years has impishly invoked the same excuse: "just kidding."

Unfortunately, his off-the-wall assertions go unchallenged most of the time. Limbaugh has thus proceeded to regularly make outlandish pronouncements to demonize his opponents -- environmental and otherwise. Typical are past assertions that Al Gore opposes internal combustion automobiles on environmental grounds; animal rights groups believe that animals are superior to human beings; the Sierra Club wants to restrict American family size to two children; Greenpeace has a prominent member who is a Hitler sympathizer; the notorious Unabomber was an environmental activist; and environmentalists want to return us to the Stone Age.

Satiric overreach was even implied as the alibi for his most recent and perhaps most publicized offensive hyperbole, a sexist slur against a Georgetown University Law School coed for defending subsidization of contraceptives.

So there you have it. In the rare instances when he is forced to produce evidence to support his broadcast diatribes and vile personal attacks -- evidence that he does not have -- Limbaugh shifts gears and professes he was merely engaging in satiric humor to make his point.

This excuse might hold water if he were a comedian regularly making a living through well-advertised off-color humor. But Limbaugh presents himself as a serious political commentator, an image embraced by his loyal listeners, who also accept his faux apologies at face value. Upon reflection, maybe they should not take him so seriously.
