Followers of Judaism and Islam have a tradition of separating women from men in several different scenarios.
The Oscars example you gave doesn't make sense, because culturally, we do not separate women from men, nor black people from white people because we are not Jewish or Muslim, nor are we living in South Africa in the 70s.
It would be outrageous for an event (using your Oscars metaphor) to separate black people in the audience from white people, and yes - if it ever happened, there would rightly be a storm of protest...and the reason why is that there is absolutely no social construct for it.
It wouldn't make any sense.
There are a whole host of social practices that those with faith follow that are not applicable to the rest of us. For instance, if the British government decreed that all forms of birth control and abortion were to be made illegal, there would be an uproar...because this isn't a Catholic country.
However, because of religious observance, in Catholic countries, this is accepted without question.
Do you see the difference?
By the way, would it be possible for you to enter the debate without chucking insults around? It only makes people want to insult you back, and that really doesn't get us anywhere.
