“He is the grandson of the late American gedol Rabbi Yosef Eliyahu Henkin z’tz’l”
But as anyone can tell you, he is not at all his grandfather, not in psak and not in hashkafah.
Generally, the crowd services by Yoatzot are not the ones heeding to the calls for tznius, so that claim is utterly bogus.
However, this is probably a good program because otherwise many of these feminists would completely abandon taharas hamishpacha. Desperate times call for desperate measures.
