The trouble, as I see it, is that you seem to assume that "equality" equals sameness.
Men and woman may be "equal" but they are not "same".
They have different needs, wants, attitudes, fears, strengths.... not that men don't differ from other men and woman from other woman, but there are psychological and physical generalities that separate the genders.
Refusing to offer a woman's only class is failing those woman, IMO. They are different and should be treated as such under appropriate circumstances.
"Separate but equal" may have a historical bad rap, but it has it's place.
Still happily answering to the call-sign Peetza.
You do not HAVE a soul. You ARE a soul. You HAVE a body.
He is no fool who gives what he can not keep to gain what he can not lose.
