“While there were changes in the mesora over the years I don’t think there were any valid ones that promoted “modernising Judaism”” I don’t think
Anyway, mo does not make sense to me. it’s basically taking judaism and tweaking it to better fit into goyishe society. Basically taking the three (or at least one or two of them) things that the generation that left mitzrayim were praised for keeping and leaving them out of judaism. (yes, i know, it’s within halacha. Please!)
As Joseph says, modern orthodoxy is gonna dissapear eventually
That’s because people eventually realize that they’re not being fed the real thing. Just like reform and conservative are pretty much non-existant anymore.
