So let me see if I have the crux of your thought here hazlnut. It's ok for commentators to spew garbage against Geroge Bush, ala, Hartman, Schultz, Rhodes, and Miller. It's ok for them to say anything they wish against American interests during a time of war when American men and women are in harms way. It's ok to misrepresent, distort, and outright lie about a political position as long as it is coming from a repub. Let's face facts here. And the simple truth is that radio talk show commentators get audiences, and keep them listening day in and day out through the use of colorful hyperbole on both sides of the political spectrum.
The man is an icon in talk radio, and in the lines of his show he has offered constructive criticism, the problem is that although liberals have talk show hosts that spew the very same type of rhetoric against conservatism, they just can't stand when they get what they dish out.
Of all the people to interview Limbaugh and actually get him on the ropes, I was surprised to see William Shatner ever so calmly corner Rush with logic on the issue of health care reform. But he is and will always be the Captain.
I haven't seen that interview, but I know that Rush has talked of it on his show, and "on the ropes" is not how it was described at all. In fact I think you may be seeing what you want to see in that regard.
