“The Chachomin according to the Rambam are ovar on Baal Tosif if they say fowl is assur biblically to eat with milk”
What’s the mashal to this thread? If you’re saying that the entire Sphardish oilam is over bal tosef by avoiding fish and milk, then obviously you know you’re wrong.
And, don’t let RGP troll you into making a argument you don’t even actually mean. Just because the anti-BBQ thing is silly doesn’t mean such a concept of “non-Shabbosdik” and oneg Shabbos don’t exist.
