I came across some interesting Youtube clips by the above-mentioned Rabbi, ( http://www.sa-hebroots.com/ ) who believes that Yeshua is the Messiah, but does not consider himself a Christian. It was a little puzzling, and I thought he must be heir to the ones that Paul scolded in Romans ch. 2.
But this article from 1990 sheds more light on the mystery. The site it appears on is down, and only this cached copy remains. The article also mentions the "anti-missionaries." Perhaps they were the ones that shut the menorah.org.za site down.
