Very convincing post.
I do have a problem with one thing though, and that’s thinking that we’re in Galut because of mistakes in pronounciation. With all due respect to the Rabbi in your last paragraph, do you honestly think that God will only accept a prayer that’s pronounced one way and not another?
I’d think that it’s Sin’at Chinam and so many other sins that put us in Galut and that’s what’s keeping us in Galut too.
That said, I say “ah”–Sephardic havarah and I like to believe that that is the correct way.
