Dear PinchasC 

Thank you for your input.  However there are many reputable and notable sources attesting to the existence of numerous extremist messianists - also boreinuniks and elokists.  Berger and others discuss them at length, as do the two notable sources (one from Haaretz no less which you removed.

I think it is fair to mention these strands in the article and certainly reasonable to do so in the light of the numerous sources.  Certainly the sources should also be kept.  This is all in line with wiki policy as far as I can make out.

The Lubavitcher Rebbe as a god, Saul Sadka, Haaretz
A Brief History of Lubavitch Messianism, Melech Jaffe

I do agree that Yechi should be merged into this article and not the other way round.  I notices the Yechi article and thought it quite absurd that there was a Yechi article but no Mishichist article.  So I thought to rectify that.

Thank you again for helping out.
