I lost the count – how many votes for or against stone-drinking. I am for and against Avira’s notion of turning around “common sense”. On one hand, my father A’H used to say similarly “if majority is for this, this is (probably) a wrong thing to do”. [not to reject, but to investigate].
On the other hand, depends how you define “common sense”. It indeed could be based on assimilation of foreign ideas and wrong as described, but sometimes common sense (aka “peshita”), when well grounded in facts and logic, is a good defense against pilpul that can lead you afar. Or a shorter version by R Twersky: hard to heal a smart alcoholic, who fools himself.
In this case, if one prefaces his halakhic pilpul with middos and detrech eretz, then you can easily conclude that it is very possible to fulfil mitzvos of Purim without getting drunk, and given the negatives, one should do exactly that. Then, you don’t need to throw Sh’A quotes at your learned teen, but just tell him – continue being a mench.
