One possible reason for mutual misunderstanding is that you and your opponent address different communities. I would question whether Rav Soloveichik would suggest opening a similar school in boro Park. To the best of my knowledge, he did not. Similarly, people from different communities can not comprehend his approach.
PS a case of society affecting halakha from Daf Yomi Tannis: community fasts and davens for rain and gets it. It then stops the fast and says Hallel Hagadol. Before hallel, in Israel, everyone goes home to eat to say Hallel in the proper satiated state. In Mehuza, Persia they’ll say Hallel before dinner. Why? Because in Mehuza they might drink too much at the dinner (to prevent the drink driving back to shul?)
