The fact of the matter is I have asked for Proof this is the the halacha and the only answer Ive gotten is
“Its a Chumra”
or
“Hashem Loves this Practice”
Yes, but you are confusing issues.
You are asking now what the source is, because you want to make a halachic argument that it is not necessary.
Earlier you argued that since it is not necessary, the motive must be to degrade women.
However, your disagreement about the necessity does not make the motive degradation.
I’m still responding to you in case anyone else is reading this. I think you are so completely bigoted that there is no chance of convincing you. You have stated that you go to meah shearim to gawk at us as if in a museum. You have stated that separate seating is equal to lynching. This is truly a case of the pot calling the kettle black. ??? ????? ????? ????.
