Babylonian Talmud, as well as Yerushalmi Shas, are the source to all the Halachos and many Minhagim. Although I have a question, there are some times throughout Shas that we find one Amora saying to another Amora something undignified. Such as this Gemara, Sanhedrin 59b, where Rabbi Abbahu calls Rabbi Zeira a "Foolish Bird", that's like calling someone now adays "You stupid person".
בעי מיניה ר' זירא מר' אבהו ירדה לו דמות חמור מהו א"ל יארוד נאלא הא אמרי ליה אין דבר טמא יורד מן השמים:
R. Zeira asked R. Abbahu: What if something in the shape of an ass were to descend? — He replied: Thou howling yorod did they not answer him that no unclean thing descends from heaven?
I'm curious, should we be acting like that to one another while asking a question which we can refute?
