I'm not sure what your subject is implying, but... He never 'mocked' talmidei chachamim, he didn't mock Orthodox rabbis, and if he did criticize a teaching, he didn't name names. This has been my impression from all that I've seen of Rav Kahane. He mostly just mocked the reform so-called rabbis for their disdain for anything Jewish (reforms encouraged intermarriage, bagels and lox identity, no shabbat, etc). Most of the things you see him criticize in this video about the "rabbis" are things an Orthodox rabbi would NEVER teach. Also in this video the guy he names names with is a person who personally attacked him in the days leading up to his event.
