@sechel83 You are being intentionally misleading when you say “Chassidim”. In this thread, no one is attacking Chassidim, rather certain practices and beliefs that are exclusive to Chabad. You’re trying to hide behind the Misnaged / Chassid machlokes. (there’s a different thread where a user is attacking Chassidishkeit in general, especially the Ba’al Shem. Maybe you have the two confused?)
But yes, you are correct. Before the tzaddik Rav Menachem Mendel Schneerson ZT”L went to the Oilom Ha’Emes, people criticized Chabad for making a huge fuss and telling the world that he was Moshiach (which he explicitly denied and told people to stop, and I’m sure there’s a teretz as to how to interpret that particular response). After he was no longer able to move or respond, and certainly after he was niftar, the frum view of Chabad messianism went from “silly tipshim” to “dangerously close to heresy”.
