““So now davening b’zman, not eating before davening, sleeping in the succah etc. are mistaken behaviors which chassidus came to fix???”
That is not what I said.”
How not? Seems to be exactly what you said. He even copied and pasted.
If the point of Chassidus were to destroy minhag Ashkenaz and eventually minhag Sphard and convert everyone to invented, Chassidic minhagim, then yes I would have no problem saying that I am unequivocally opposed to Chassidus. BUT, today, Chabad is the only group that behaves that way.
