sechel: Now before attacking chabad think of these 6 things. Very simple!
I find it interesting that you were never upset about the lashon hara when CS wrote a number of times how others look at their Rebbes, how others tznius is only for show and the like. Or is that why you wrote “before attacking chabad…?
And to address the point directly, it is a mitzvah to forewarn people about individuals and movements that lead others astray, and Lubavich with their messianism, claims to prophecy and nesius are doing just that. What it says in Kesser Shem Tov is not referring to misleading people or movements. If it was Lubavich would not have been able to publish a booklet about the Tzemach Tzedek’s fight with Haskalah, as well as a lot of the stories in the Rayatz’s Memoirs.
