Sure we’re arguing. I’m saying the minhag started from poskim deciding that for some legitimate reason (later generations tried to figure out that reason) it was better halachically to not duchan.
You are saying that some am haaratzim decided not to duchan, the rabbonim didn’t stop them, and later generations lied and said there was a reason, but we can see right through them, because we know the reason they give doesn’t make sense..
At least that’s what it seems to me that you are saying.
It’s pretty much the same argument we had about shlissel challah.
