From the paper:
> moral authorisation has to come before the imposition.
What's the expression... tell me you're a Millennial without telling me you're a Millennial...?
The anti-natalist movement and it's reactionary natalist counterpart are perfect case studies in how people's beliefs are shaped by their cultural environment.
Given all that, it's expected that a large number of people--in particular, those of the same or adjacent generations--would share these beliefs and even analysis; and an even larger number sharing similar framing, even if coming to opposite conclusions.
It's disquieting when you come to the realization that so many of one's beliefs are, in a sense, predetermined, or at least channeled by a cultural experience shared with millions of other people. This of course applies to myself no less than any other. I long ago stopped considering any of my thoughts rare, let alone original. I read half of the literary output of people from my generation and think, "gee, I was saying that 20 years ago"; and the other half, "gee, I was arguing the opposite 20 years ago". Well, of course I was, and so were they.
That's not to say there aren't novel exceptional moments, cases, and people. Just very few and far between. And the whole natalism debate is definitely not the exception.
The wikipedia article from where I snagged that quote has a few more examples that go back to like, ancient Greece. Check it out!
P.S. it does sound like you have at least a mild disdain for millennials and also an opinion on the matter - share your thoughts, tease out those details! dismissing a topic as a generational "odd thing" isn't fun, and is definitely a common and unoriginal idea.
