You'd have to be willfully ignorant of context, history and systemic power dynamics to think misandry is a threat to men in the same way misogyny is a threat to... well, everyone.
That is not misandry and it doesn't even matter because the imperialist powers that use it to justify killing civilians are just as comfortable vaporizing women and girls.
(CW: Violence, gore) It's important to note that a lot of who they classify as a "military-aged male combatant" is done after-the-fact, and it's often difficult or impossible to tell the sex/gender of loose bodyparts in a field.
A patriarchal society being both misogynist (women can't fight) and classist (send the poors to be cannon fodder)
Reminder that women have fought in every war and their contributions always go largely ignored. British women who fought in WW2 against the Nazis found that when they wear their medals in veteran parades, they are often subject to idiots screaming at them that they're "wearing their fathers medals on the wrong side" the idea that the medals are their own doesn't even compute.
