Da’Moshe had an excellent point regarding the underlying assumption of this thread that any comingling of the genders at chassanahs will lead pritzus, raise issues of tzinius and giluye arroyos etc. He notes that
Rav Yosef Breuer, ztz”l (and some other chashuve rabbonim not all of whom were Yekeshe) strongly opposed to the practice of separate seating at chassanahs. He correctly noted this was a relatively new Americaneshe minhag and was not the practice in the alte heim where perhaps except for certain chassideshe courts mixed seating had been the general practice in Eastern Europe. The Yekkishe practice. was to have four married couples to a circular table (withno man sat next to another’s wife and with singles deliberately mixed so that young men and women could socialize with each other.
Given that the fundamental biological, hormonal and yetzer harah DNA cannot have changed so quickly, If it was good enough for the Alte Heim, why is it not good enough for chashuve askanim like Joe??
