This article by the Jerusalem Post speaks out against Dov Shurin and his brand of zealots. He quotes the Chofetz Chaim who "had harsh warnings against entertaining hateful feelings." I found this article a stark contrast to this one which seemed to enjoy his live version much more.
This reminds me of a song I had heard on the radio as a child. The song was written by Dov Shurin concerning the dangers of watching TV and it went like this:
Television is tamei (impure), television is Tamei, Avayros you will get, mitzvahs you'll forget....
take an ax and whack that TV set (swish) BOOOOOOM!
What a comical song, wish I had an audio clip.
