Jammer, you seem to have missed my point entirely.
You're still responding as if those who disagree with you were saying that women must be segregated, which isn't remotely the case. It is you who are saying that they must be taught in the way you regard as politically correct. Others are arguing in favor of offering choices, and allowing the customer to pick the one that she prefers.
I'll repeat the question I asked you, and I'll even add some italics and whatnot:
How is it unethical to offer people a range of choices when the result is to increase their freedom?
If you don't believe that women are entitled to decide what best fits their needs, then you're either belittling them in a pretty big way, or you're putting an abstract principle ahead of their right to self-determination.
