I believe it is perfectly proper.....and it has to do with being an American not a liberal
By law, Rush has a right to appear on the radio and say whatever he pleases. The constitution says he can't be prosecuted, that is the only protection it gives him
Just as Rush has freedom of speech, people have freedom of association. Those who love what Rush has to say will choose to associate with his sponsors and the sponsors will make money.
Those who are offended by what Rush says will tell sponsors they will not associate with them and sponsors lose money
It just becomes a business decision for sponsors
It is kind of anti-American and it is a liberal contradiction to endorse what Media Matters is trying to do.

The GOAL is to silence the voice of the man. And it is NOT over the fact that he called Ms. Fluke a "slut." So very many on the left speak in very similar terms all the time about women. So we know it isn't the word "slut" that motivates these charlatans.
Clearly, it is just an opportunity to exploit in order to silence him as a spokesman for the political point of view they detest: conservatism.
When a liberal tries to silence the opposition, and in doing so REJECTS the "free market of competing ideas," that liberal is no longer speaking as a liberal.
You guys really do need to re-think this. But liberal dogma and orthodoxy will not permit you to do so.
