If the Viznitzer Rav had a problem with Rabbi Lau, he should have made them months ago. You dont make demands 2 weeks before an event.
He is not the one who invited him. I do not know when the invitation was offered, accepted, and announced, but I didn’t know about it until a couple of days ago. You’re right, though, that there was lack of aforethought in inviting someone controversial.
If people would be as strong about keeping the Torah as they are about being anti Tzioni
Are you c”v accusing the Vishnitzer Rebbe of not being as strong about other parts of the Torah as he is about being anti-tzioni?
