A lot of people have told me that for many years they have tried to get so drunk that they don’t know the difference between arur haman and baruch Mordechai, but that they have never been able to get that confused no matter how drunk they get.
Assuming that one takes the position that the mitzva is in fact to become so utterly stupefied, how is this not a davar she’ain rov hatzibur yachol la’amod bo?
