The reason Limbaugh along with other conservative loud mouth talk show hosts spark outrage in most level headed folks is that they're phonies. Conservatives have some valid points to make but when they allow this blimp to be the mouthpiece of their rhetoric....you have no rhyme or reason to whine when Obama gets another four years.
THIS.
I have worked with guys who espoused all the usual talking points, etc, etc, but if the audience knew the way some of these guys carried on in their personal lives, they'd be shocked. Many of these hosts are hypocritical paper tigers. The audience is often either to naive, ignorant or blind to allow in any light should any of this info actually ever get to them.
Ironically, I was always more measured in my opinions, never adhering to some partisan credo, yet I was always considered the "liberal" because I didn't march in lock step with the Rush immitators. I actually thought for myself. Ironically, I typically led a much more "conservative" lifestyle and behaved in a much more conservative manner than the "real" conservatives on the air.
Truth is irrelevant. Only feeding people's ego's is what's important. People want to believe their little world view is the correct one in ALL circumstances, and no matter how flawed and hypocritical the enabler is, they'll buy what he has to say; hook, line & sinker---as long as the conclusion is that YOUR side is RIGHT!
That approach does, and always will, cater to the lowest common denominator.
