Re, the kusi – that was my mistake. I was going through medrashim quoted in an article and read it too quickly.
You didn’t address my other points on the ibn ezra/rav saadya. It’s unthinkable that they would refer to an amora as either “one of our nation” or “chasirei daas,” even when arguing. That’s never the case when the rishonim differ from chazal in pshat – they always speak respectfully, as chazal were chachameinu, our sages who gave over the Torah that we have.
My point about rav saadya being in Arabic is that the expressions used might not be very clear, plus the piece is missing words – maybe there were other errors that fell into its printing too? I also don’t know who the magiah is – do you?
You also haven’t addressed the clear psak of the aruch hashulchan and what gave you the authority to pasken on a sugya based on your own decisions, when the issue at hand is lf grave concern
