Popa, why do you say that? It doesn’t seem like you’re joking, so I’d just like to advise you that inflammatory statements like that do not add to the achdus of klal yisrael.
Regarding the metzius itself, you think it is better for someone not to learn ANY Torah their entire lives rather than diligently and meaningfully learn gemara, rishonim, shulchan aruch, or other Jewish texts from a knowledgeable guy like rav linzer? Halachically, that seems problematic as every minute of Torah is worthwhile and David Hamelech even learned from Achitophel, a far less decent dude than Rav Linzer!
Also, when YCT rabbanim teach gemara shiurim, for example, correct me if I am wrong (based on your first hand knowledge) but I do not believe they are teaching it with any particular agenda in mind, just like Brisk, Vizhnitz, and YU don’t have political agendas when learning shas and poskim, they simply go through the gemara as Jews have done for thousands of years. YCT probably saves their politics for a different time, which is why it’s so machlokesdik and unfair to say their Torah learning is not real learning.
A question to ponder: I know of a conservative rabbi in my community that reportedly went through the entire Rambam Sefer Ahavah. Is it better had this non-frum guy (who I personally wouldn’t call rabbi, per rav moshe) not learn at all?
