I sympathize with him. I don't have my own Youtube channel (actually I do, but I don't upload videos on it) but there's plenty of mouth-breathers and trolls out there on the interweb unfortunately, and many of them choose to hang around Youtube. (Try posting on the IMDB message board for Breaking Bad sometime as well.) What can you do? Just hope that someone with good taste and half a brain happens to find your channel and has something relevant to say about whatever video you upload.
I might try and find his video on the Hogan/Piper Starrcade '96 issue though because I disagree with him thinking it should have been a title match.
