Sam2 my question is not did any sages ever say that.
My question was if they did, why did it not become common and accepted
teaching in the big and prestigious yeshivas down through the centuries?
There must have been some reason why this was not taught to the average student in the average or more prestigious yeshivahs.
When a rabbi states unequivocally that the Earth is fewer then 6000 years old and that humans do not share common descent with any other life form and then scientists claim we did, to say Torah says it’s possible is a reinterpretation from what all those rabbis teach.
And yes the whole “we don’t need to eat meat or wear fur beacuse it is (supposedly) cruel, is largly if not all, because of supposed modern enlightenment.
Same for MBP which is championed by the Toveia marrige crowd.
These things were not so cruel or dangerous 200 years ago that the rabbis forbade them, when
We had no modern transportation for chickens or sterilizing sprays for surgical utensils.
I was told that (I believe it was) the Rema said that the blood of Bris Mila was to be spit out on the floor, which obviously means it had to have been in the mohels mouth which back I was told by the (older and long married, ie: not a kid) son of my rav that is the basis today for MBP.
