This R' Malkiel Kotler, used to be a meek "chechele mechele" ... and as the Yiddish saying goes, "nisht kein groiser chuchem in nisht kein kleiner naar."
He became the chief Satmar tuchis lekkeer, supporting the bizarre Satmar SHIT'ah against The State of Israel, and publicly endorses the Auerbach "Peleg" crazed fanatics who illegally shut down roads in Yerushalayim and Bnei Brak ...
But what was understood was that he chastised the guests for their
non-support of Peleg violence!
The Noveminsker called him out on that in his Keynote address on Motzei Shabbas!
R' Malkiel is also a supporter to those who advocate killing Jews by contaminating Jewish communities with Measles! He is what they call an "anti-vaxxer.!
To support his crazed dangerous idea ... he tried to recruit the great poisek Rav Moshe Sternbuch.
R' Malkiel thought wrongly that he would have Rav Sternbuch's support because of his mutual hate of the State of Israel!
Turns out that Rav Sternbuch is a strong supporter of vaccinations and in fact ruled halachically that everyone in Israel is obligated to get vaccinated and that Yeshivois have the right to refuse entry to any child that is not vaccinated!
Below is a copy of his Psak and his lengthy detailed answer addressed specifically to R' Malkiel!
And translated in English!
