Rava critiques Rav Nachman for expressing his like/dislike of certain halachos. But don’t we find many times (Shavuos 45b etc.) where the Chachamim would praise a specific halacha, and at other times negate and dispute others?
“Ein ma’avirin al ha’ochlin” the Gemara seems to apply this to all foods. Since the subject matter in the story was ‘Gluskin’ (bread/baked goods) perhaps this only applies to items such as those – which carry added significance (Hamotzie, food staple etc.)?
