Women's lives are valuable, men's are not. This has been the case across basically all societies in human history. Losing a ton of men really doesn't matter too much - especially young, family-less men.
Losing a lot of women, though, is really really bad.
Isn't that reinforcing a gender stereotype? I was told we were against that kind of things around here.
This isn't sexist, it's reality. It's the rationale for male conscription and male disposability.
