Da, do you similarly not believe in the Arizals kabalah, because it was largely revelation based?
Litvishe have a mesorah from the Gaon, which was at the same time as the baal shem tov. Talmidei habaal shem said that their ways were really old, and the truth is that many chasidishe ideas can be found in other places, such as rabbeinu yonah.
You haven’t addressed my issue with your jumping to conclusions about chadidus because an individual man, not a rosh yeshiva or rov, couldn’t answer your kashos.
I had kashos on tanya and other seforim; did you even bother trying to answer them yourself, or did you come into the seder with preconceived notions against the seforim? You should treat a chasidishe sefer with the same seriousness as nefesh hachaim; I’ve asked kashos on that sefer too, and nobody shies away from answering them.
There are virtually no gedolei yisroel today who agree with your idea that the baal shem tov was simply mistaken or that people shouldn’t follow him. Later chasidusen didn’t move away from chasidus, they simply taught their generations. There was a time for a certain avodah, and there was a time for kotzk. There’s also a time for today’s chasidus.
Chasidus is about taking kabalah and using its ideas for avodas Hashem, in not a very different way than baalei mussar taking maamarei chazal and medrashim for the same purpose. One chasidishe gadol said that rav yisroel salanter does for the litvishe what I do for you. One of the gerrer rebbes told his chasidim that rav hirsch does for the yekkishe what i do for you.
Classic Chabad and, to a lesser extent, Breslov, use more kabalistic ideas than other groups; that’s the main difference.
Chasidus produced gedolei olam the likes of the divrei chaim, the rogotchover, rav meir shapiro, the sfas emes(who the brisker rov held was a massive gadol in nigleh too), the avnei nezer, the butchacher rov(aizer mikodesh on shu”a), and many, many others who were universally respected.
