Sechel > vilna gaon was fed lies by the misnagdim, thats why he made a cherem against chassidim,
could you tell us whose opinion this is? Most chassidim and misnagdim made peace by now, and I think the prevailing view is that Gaon’s position against excesses helped Chassidim to become a better movement. I think Alter Rebbe also contributed to that process.
