This conversation makes more sense now that all the posts were up, not just the mods.
I’ve never heard of Buddhism and other non-Abrahamic religions agreeing to Matan Torah either. Silence does NOT mean acceptance. Many religeons were secluded from Western religions for a long time.
Is there anywhere that they proclaim Matan Torah was true?
Rabbi Miller’s statement was not that every person that ever existed anywhere in the world believed in Har Sinai. It was that no one ever denied it. No, I am willing to bet that B**dha never declared that Matan Torah was true.
