I think that's a great example though. I'm male, and I think a common misconception is that gender equality is only for the benefit of females. But feminist issues effect everyone. Like women being allowed to join the workforce increased productivity which also benefited men from having cheaper products.
Or this example you point out, men are typically the ones being drafted into war or at least the ones serving on the front lines. I think that raises a lot of interesting questions too. Is that fair? Should women more often be included in drafts or mandatory service? Should women be included in the decisions to go to war? Would we have less wars if that were the case?
