im a bit confused by this thread but generally men just ARE "disposables", if only by the nature of man being that biologically, men impregnate a woman/en, and then the woman/en does the rest of the work. said work requires 9 months. that sabretooth is hungry, won't stop, and men are built for fighting and living and dying fast. some species are fucky but in general nature follows the same pattern of "protect the queen". a woman can easily, if she chooses, have multiple kids in their life, so even if every single one of their men dies, if the queens are protected, man wins. it's not specifically good, but it's just the laws of nature saying that that wolf pack has cute little pups and are hungry, man has little babies and they're hungry, one or the other has to go and both have honed their skills over milennia.
in terms of war itself, some wars are necessary, specifically in self defense or in cases of shit like native american raids/rapes (or them defending themselves) viking raids/rapes, mongols, specific tyrants, stuff like south africans being unable to move or desire death, but 90% of them are retarded, and for some reason anti war hippies turned into "ackshully glassing israel and russia is a grand idea". imo, the rational approach to people discussing women being included in drafts is when you have constant talks about equality, the rise of troonery (im a women now so cant deport haha), the rise of protected classes/religions being excluded, makes men very bitter, angry, grudging, with essentially people talking about how men need to buck up and are oppressive and shitty while they have to crawl through tomato paste in normandy, and (maybe) return to a dear john letter because even though john wrote betsy every day, well, betsy (waited for so long and still loves john but cries every night so has to break up) really got horny for the gas station man that mysteriously had a foot shot accident.
then returns, alone, with minimum wage benefits, and fast forward to modern day where old vets are spit on by male teens with rainbow hair and fishnets. it's a recipe for long term anger and grudges, regardless of if it's to correct targets. of course not all women or teens are like that, but you also can easily see why eventually them and people they share their stories could go "wow ok, you know what, how bout we just send antifa etc to the front lines, and fuck it, women are equals and us men are shit so they can write their dear john letter in a vietnam forest", even without any of the "old men play games with the young in a blender" talking points.
