Reply To: How come all frum Jews today aren’t Chassidic?

Some distinctions need to be made:
Chassidus, the movement created by the Baal Shem Tov
Chassidus, the set of teachings, which includes teachings found elsewhere
Chassidus, the way of life of certain Jews today
Chassidus, the trait of Chazal’s “Chassid” (as explained in Mesillas Yesharim)
