As an amateur in the workings of Gemara, and as a Jew who has just made Aliyah, this is a problem that is really biting at me.
R Yehuda's statement is obviously Aggadeta, and is seemingly refuted by R Zeira, but my issue comes from the fact that R Yehuda's opinion is never rejected outright by the Gemara, nor does he ever change it. Is this a silly thing to be bothered by? Probably. But I can't get it off my mind. How do the Rishonim completely ignore R Yehuda's statement, even if it was never rejected?
