So you learnt chassidus yourself and believe that its a good thing for people to learn but disagree with the amount of chassidus that chabad encourages. Fine. But your “proof” is simply preposterous. You have taanos against certain Chabad beliefs, but to, but to blame that on chassidus is ridiculous. Can you find any direct or indirect link between the teachings of chassidus that explain the spiritual makeup of the world, man, the Torah, Hashem, and the relation between one another, to any of your complaints listed in your post? Chabad may have its seemingly peculiar beliefs, but there are thousands who share none of those beliefs and do not identify with Chabad, yet learn the same amount and type of chassidus that we do.
By the way, chabad yeshivos learn 3 hours chassidus, and 7 hours nigla. So no need to worry chassidus “eating up” our nigla. We view chassidus as equally important b’eichus but we also learn it secondary b’kamus.
