Wait... that is what you were referring to with this ....?
Your initial post implied that women are being discriminated against. Do you not see the difference between women and men sitting in different parts of a bus due to religious beliefs vs them being separated due to women being considered to be inferior to men?
From the article you linked...
In Pirkei Avot 1:5, Yosi ben Yochanan says that a man who spends too much time talking to women, even his wife, neglects the study of Torah and will inherit gehinnom.[1]
Chapter 152 of Kitzur Shulchan Aruch details a series of laws forbidding interaction between persons of the opposite sex who are not married or closely related.[2] Some of the prohibitions include physical contact, isolation with members of the opposite sex, staring at women or any of their body parts or attire, or conversation for pleasure.
It is really not all that different from Muslims requiring women to wear burkas/hijabs.
