Well the webcam version I saw had Rush throwing his arms around and talking about how Fox was "acting", that is wasn't real. Sometimes what people do speaks louder than what they say. And you can't take it back.
Like I said, Rush is very animated when he speaks, and they SPEEDED IT UP to exaggerate it. If they're going to quote him, they should quote him IN CONTEXT, not slice out the parts that fit their "Rush is a heartless a$$**** for picking on poor Michael J. Fox" mantra. If you listen to him IN CONTEXT, that's not what he was saying at all. The part with him describing what the ad looked like to him was less than 10 seconds out of a one-hour discussion. The media took it, lied about it, and beat it like a dime-store drum.
