I see some MRAs here and elsewhere pointing to the injustice of society seeing males as disposable in a particular fashion. They allude to the evolutionary reason why males might be viewed as disposable which is that they are not a limiting factor in population growth. Then they go on to say that such a consideration is nonsensical today as the world is filled with 8 billion people. I have seen quite a few people cite this reproductive "reason" as a form of outright justification of male disposability. They of course miss that just because something is evolutionarily viable doesn't make it moral. So a justification which necessarily is a moral justification can never follow from evolutionary-reproductive "reasons". That is of course their moral fault. But what concerns me is when MRAs criticize the societal attitude in this particular fashion. They say that the evolutionary "reason" is nonsense TODAY because there are 8 billion people TODAY. Do these people then believe that depending on the population male disposability can be justified? That if somehow WW3 breaks out and human population dwindles, the people born males will then be viewed as lesser and disposable and it will be justified just because the species might face extinction? This concerns me and this is posed as a question to the people here.
