This is true. If Rush had made liberal talk radio popular and had done a death update of a disease affecting fundamentalist Christians, the same people laughing about his death now would be mourning the great progressive titan.
I for one will not condemn Rush for the political positions he took on the air. What I will criticize about his legacy is his contribution towards radicalizing American politics. It doesn't matter what side of the spectrum you're on, if you're whipping that side up into a froth it's bad for American politics. It turns everything into a moral issue. Any compromise is total defeat. It breeds distrust and actual outright hatred of those who disagree with you.
Radicalizing one side also has an effect on the other side. Like it or not the left is more radical today because of Rush than it would have been otherwise. Movement one side towards the extremes is generally met with an equal movement of the other side in the opposite direction. By pushing the right farther right, it moved the left farther left.
That's what I don't like about Rush's legacy. However, that's no reason to celebrate his death. Disagreement doesn't make him less human.
It’s the chicken or the egg question. To act like the left wasn’t radical before Rush was born to the earth is flat out wrong from my understanding of history.
Then it becomes what do you do in the face of such radicals? Sit there and hope you can win an ideological war of ideas like the Romney/Mcain strategy? I think we’ve all seen that doesn’t work.
