Torah im derech eretz, a mahalach based on a mishnah, has nothing to do with “Torah” umada, the unsourced ramblings of ignorami who equate, chas veshalom, Torah and algebra. Rav Hirsch called the chochmos the handmaids of Torah, not anywhere near equals, nor important in and of themselves.
Have any doubts? See rav breuer, rav shimon schwab, and other yekkishe rabbonim, heirs to Torah im derech eretz, who are more anti YU than most litvishe.
