Wolf,
There are no instances in the Gemorah of Chazal being wrong. Period. It is indisputable that what they say is from a divine source. Period. You cannot dispute the word of Chazal. Period.
As far as the infallibility flap-up, I do point out you have used this term in the past, indeed you brought the term into this very conversation. And the subtle, albeit sometimes not explicitly stated, implication when bringing up the “infallibility” issue, is that your opposing conversationalist is making someone out to be infallible like the pope. That is a lie as I pointed out. That being said, I apologize for ruffling your feathers… err, fur.
