Oomis where these Rabbonim form their opinions from I have no idea, None of them are quote on qoute mainstream Rabbonim for a reason. Basically it’s straight out Shulchan Aruch women may not be counted for a minyan (orach chaim siman nun daled if i remember correctly)
Furthermore let me make it perfectly clear for one to take it upon themselves to rate a Yom Tov established by Chazal is naive, foolish and dangerous.
Furthermore when you continue on your diatribe against drinking on Purim please take a moment to remember that the plain meaning of the Gemora is that one is required to get drunk on Purim.
It is one thing to say that perhaps in light of certain risks in keeping with Pikuach Nefesh and other halachic principals we are required to examine alternitave shitos explaining this Gemora most of which start whith a Bais Ephraim.
However it is quite another to say the very act of drunkenness on Purim isa a Chilul Hashem. When one does such a thing they show thier barometer of proper behavior is not that which has been laid down by Chazal rather it is that of the nations in whos midst we find ourselves.
Thier can be no greater Chilul Hashem then subjecting the teachings of Chazal to the morals of the goyim.
In closing I would urge you to take heed of the words of Rav Shamshon Raphael Hirsh zt’l who began his famous nineteen letters by stating firmly and clearly that when one studies the Torah one must study it as a Jew not in a dispassionate way.
So to when we study Chazal we must study it as Jews with amesorah on each and everything we do including how we celebrate Purim.
