Media Matters has rarely struck me as being all that well thought out (on purpose; just wear them down, as Rush tries to do from his side), but Rush Limbaugh's commentary about Sandra Fluke was deliberately over the top. He let himself in for an attack by the likes of Media Matters.
Really, that level of "activism" is pretty trashy and pushed openly hypocritically. Limbaugh and Media Matters really are on about the same level of discourse.
I'm not asking people to be stuck up, but if one is going to be sarcastic, can it at least be witty and not thrown out there by people in glass houses?
