"If you're not a Feminist, you're a Sexist"

[DeistPaladin]

Do you not hear yourself? Men are expendable? Really dude, really?

I said, "if need be, we are the more expendable". This is true from a reproductive standpoint as well as a psychological one. A society that loses half its male population will recover in a generation. A society that loses half its female population is decimated and will take much longer to recover, if it ever does. We are psychologically also wired to be the protectors of women and children, placing our bodies between them and harm's way. It's what we do.

Societies may vary on some of the other issues you hyperbolically brought up. Some may treat women equally while others regard them as chattel, per your example. But what remains unchanged in every example I know of is "women and children first". It's the golden rule that stays in place when the cities are burning, the land is overrun and all else needs to be dumped in favor of survival. When things really get bad for a civilization, when most of the men are dead, the women will take on a similar role guarding the children, risking their own lives as need be.

Sorry, I know this isn't politically correct to say. I know every time I point this out, the PC cops, white knighters and other idealists spring into action to deny this fundamental aspect of gender dimorphism, acting under the misguided notion that, dammit, equality requires nothing less than total and complete interchangeability!

Luckily, equality doesn't require interchangeability, contrary to the prevailing PC wisdom. Women can be equal and yet different.
