Whether it's for the military or not, I find these women's behavior gross and their followers pathetic. It feels like we're veering into post-feminist territory where attractive, charismatic women can market themselves on the internet and society can't offer a reasonable objection without resorting to social conservatism.
They've claimed that this is their choice, that this is empowering, that the alternative was slavery and oppression, but I'm not sure how many sincerely believe those slogans.
This was all foreseen and predicted. The world was warned, but the world pressed on blindly.
Women in many cultures and times were just seen as baby machines and failing to have children often led to intense shame especially if the women failed to produce the right gender. And for those with unwanted pregnancy - suicide was a common option either by failed abortion, or trying to make ends meet in other ways, or just straight suicide I read quite a lot of stories of it. People made things work or just didn't and finished it quickly, they were expected to and I'd say that the concept of love was a lot different then how we think of it now. People did things because they were supposed to (or were forced too), not always because they wanted to. You can look at any time in history and see this, the Bible has a ton of examples of poor women in bad situations (Leah & Rachel, Hagar, Bathsheba, etc). It also even brings up when to abort a child as a way to prove guilt or innocence of sleeping around (Ordeal of the bitter water.) But you find concubine stories, slave stories, multiple wives all over the world, ... Women historical were often treated more like children or objects then treasure. The Bible also shows cases of women in power too (Deborah, Miriam, etc) and the love of them is mixed. I'm just saying you might think it's a 'modern problem' but it's always been a part of history. Conception has always been around too even if not well understood, the rich having the best access.
I do agree that relationships nowadays can be much cheaper though but for particular generations like millennials for example sex in general is at an all time historical low. I'd say in general more people are afraid of relationships then anything due to money, family trauma or many other cases be it America, Europe and Asian countries. It's more stress and fear related then anything I'd say besides the devaluing of children (in cities they are an expense, on a farm an asset). Plus with many families separated because of work, it's harder to rise children with lack of community in many places.
