No, I saw the video, he definitely did. Why would you even ask that? I never insinuated it didn't happen.
The proper response to a single "liberal heckler" is to call out that heckler, or call out his boss, or call out his news station, and remind people that an independent (and ideally, civil) media and proper discourse is fundamental to a well functioning democracy.
You don't send an email blast out to the entire country (specially to his supporters) saying, "see, because of this one guy, we should get rid of all independent and publicly funded news, and you should all just let us, the wise and benevolent leaders of the CPC, tell you what's true."
