Sex slavery isn't considered acceptable at all. All the exploitations of men are. And in fact sexual abuse is only considered bad when men do it, when women do it it's okay apparently, if we're even willing to admit that they're capable of such evils.

And with regards to military service...there are plenty more jobs other than the ones that require macho man strength. The real reason we're unwilling to put a woman in any position of danger is because her death is far more tragic to our primal minds, as well as any trauma or harship induced. The response to a woman's cry is similar to a child's, to rush to help. The response to a man's cry is telling him to "get over it and shut up". There is a clear difference in how much we care about women vs men.

I think women were too overprotected and silenced and treated like children in the past, but we're over that. And they still get all the benefits of being treated that way and get to have their cake and eat it too.
