“I would extend this: the chosid might say – I am on the way to the hospital for bikur cholim or on the way to kollel and learning is keneged kulam.”
So we should stop practicing our religion so we can focus all energy on attracting people back to our religion which we don’t actually practice? I think you’re mixed up on who the “chosid shoteh” is here.
I know you’re not going to listen to me, so maybe talk to whoever in Chabad is clearly influencing you, because even they would object to what you’re saying. Nobody says everyone should be mevatel other mitzvos to focus solely on kiruv.
“Chasam Sofer did not live there.”
He lived between France and Russia, and he presumably didn’t think Napoleon was going to jump over central Europe to reach Russia. Stopping his advance in central Europe means stopping before Russia. Anyway, as I said, I’m sure there are exceptions. I have no idea why it is so important to some people to believe that the Baal Hatanya was a daas yochid on this issue, especially given that it isn’t so cut and dry that Napoleon would have been the worse outcome for the Jews.
