I don't really think that it's something that's neccesary. That being said, in many countries it is not uncommon to have optional segregated seating. Japan has entire women only compartments. I see this as a reasonable accomadation to peoples wants/needs. I have heard though that women can be quite cruel to each other in a homogeneos group.
