What amazes me most about these things is where was Rav Wolbe - lemoshol - when the Rebbe was ridiculed for this very idea?! There were also others who were alive who probably remember the CC wanting to do it, why were they silent? Why did they not stand up and sign on to the idea?! Does the idea suddenly become treyf once Lubavitch pitches it? The Rebbe obviously saw that times have changed and the goyim will listen to the call for them to keep the sheva mitzvos.
