I know frummies love to use this gemarah, but I'm sorry to inform you that this gemara is not paskened lehalacha in Shulchan Aruch.
that is utter nonsense
Besides, if you learnt pshat correctly instead of just repeating slogans you'd come to entirely different conclusions.
do you have a source for a different pshat than the literal one and the one that many learned rabbis from previous generations have learned?
Wow! So whoever uses the term נשטתנו הטבעים or נשתנו העתים is ipso facto a kofer.
you will rarely find those terms being used its a very delicate issue and the guidlines may vary, i have heard different shitos as to exactly when we can say it. but according to no definition can one apply it to our disscussion
Kofer in what exactly?
chazal
Do we still keep our women locked up the way the Rambam says we should? or do we say that times have changed and women today are a normal occurrence on the street?
untill this line i was under the impression you may have some background yedios to your point, what does the rambam have to do with being koifer in chazal? nowwhere does it say that a psak from the rambam or shulchan aruch ect... has those guidelines on the contrary we find that it can be said about them that a taos was made
