Its funny how you think the Litivish/yeshivish world is mainstream klal yisroel…do you really think that it is the same as the time by the Gaon?.Its also funny as how you accept the Gaon but not the Baal Shem Tov for some reason as authority on matters.Its also funny that you decided to make this a topic because even if you accept that the cherem still stands,you will do nothing about it.
I am a chossid.BH.I love the Vilna Gaon.Opposite of whatever he was trying to accomplish.
