Dude, a lie requires intent. You already labeled the man an "ignoramus", you have told us you forced yourself to watch the video, that is on you, and now you want to kick the "clown" while he is attempting to apologize and calling him a "liar" without offering any proof?
Shall we burn him at the stake with this pile on?
Everything here about his previous video is self-evident for the astute.
You are crossing a line of civility, and for what exactly?
None of us here are perfect and few of us are man enough to even attempt an apology, from my life experiences.
