Crying apikorsus is just low and unintelligent in an argument.
As opposed to that comment?
I’m not merely saying it’s apikorsus, I’m explaining why. If you think you win the argument by calling me (or my opinions) unintelligent and a shoteh, then so be it.
I think saying Chaza’l were wrong about science is simplistic and wrong. The Gemara in a couple of places suggests “Sod Hashem li’yreov” as the source of Chazal’s statements regarding science. I hope you don’t think the scientists know more than Hashem.
But I don’t think it’s apikorsus. I try not to throw around the term lightly. But saying that their values are primitive, outdated and stolen from the goyim, and that Pirkei Avos is “a primer”, I wil say it the way it is. It’s apkrsus (or kefirah, take your pick of terminology).
