I agree with Feif Un, unfortunately that was the one very sad part about this whole wonderful event. I think that had that not happened, had all the protesters come anyway and stood up in respect for a talmid chacham when he got up to speak, mashiach would have revealed himself right there during the siyum.
About the live stream, it was a great thing for those who could not attend in person, but on the other hand, I think that it takes away from the event because people feel they don’t have to come in person, they can just watch it online. One of the great things about this type of event is being together with almost 100,000 Jews in the same place, singing, dancing, hearing divrei chizzuk, and being mikadesh Shem Shamayim. Watching it online just doesn’t compare. It was for this reason that I thought it a good thing that the asifa wasn’t streamed online (although they didn’t stream it for other reasons, a discussion for another thread)
L’havdil, like any big football game, this event was sold out so many people couldn’t come for lack of room, so you couldn’t just “black it out” online. IY”H, 7.5 years from now we will all join together in the Beis Hamikdash in Yerushalayim for the next siyum and Hashem will perform an open miracle that millions of people will all have 4 amos of space.
