HaKatan: You’re slipping!! You didn’t mention Zionism at all! Are you feeling ok?
You talk about the “questionable” piece from R’ Broyde. R’ Broyde stresses in the article that he’s attempting to be melamed zchus for the women who don’t cover their hair. However, in the piece, he stresses that it should NOT be relied upon, nor used as a heter. He stresses that married women should cover their hair! I don’t see anything questionable about that!
MO does NOT attempt to justify what they are doing. Perhaps a few people do, but I’ve never heard a MO Rav try to justify why a married woman can uncover her hair in public. You’re making things up and attacking a large group of people. You should ask for mechilah.
