PBA: To quote a very smart woman who I once asked this to, “Why should the way people perceive me stop me from doing a Kiyum Safek Mid’oraisa?” Those words made an impression on me. Why should a woman care what anti-Jewish feminists do or what others will perceive of her? Why should that association stop her from doing a Mitzvah out of Ahavas or Yiras Shamayim? (Another woman once said that to me. I noticed she was wearing Tzitzis out. I was curious about that and asked her, and she quoted the Mishnah B’rurah’s rant that Tzitzis should be worn out. I told her that it looks weird though and that people will think she’s Conservative. Her response was, “Is my Yiras Adam more important than my Yiras Shamayim?” I managed to convince her to keep her Tzitzis tucked in, but how could I honestly tell such a person, who only wants to do Mitzvos, that she can’t?)
So I will agree with you in theory. Most people who call themselves feminist probably are not actually Shomrei Halachah and they are probably actually trying to be Oker Halachah. But many who we would label as feminists are good Jews who just want to do as many Mitzvos as possible.
And by they way, most women who make Mezumans probably say Nevarech and not Mir Veln Bentschn. 😛
