Fwiu the content of many of the lectures is diametrically opposed to hashkafas hatorah. Please cmiiw.
While that is absolutely correct, the prevalence certainly depends on the field of study. Although even in fields that do involve quite a bit of content that may be keneged daas/hashkafas hatorah, one can still go into it with a proper mindset, a very serious connection to rebbeim and rabbanim, and still remain both a yarei shamayim and a ben aliyah. Again, no one said it's easy, but it is certainly possible, and I know many people who fall in this category (I'm sure you do too).
