> his opinion was based on foreign influence.
I am confused, which nation is teaching Gemorah to girls so well that they influenced R Soloveichik? If you suspect the infuences, they would surely have come from his German university training. We can presume that even if he was influenced in 1930s, he was aware of the failure of German philosophy to form a society at the end, so he would surely take that into account. Your argument might hold more for Rav Hirsh, for example, with his respect to German culture.
