Climate change is making people think twice about having children

Could you point to some examples of anti-natalist propaganda? I have absolutely no idea what it looks like. Maybe I've been living under an algorithmic rock since I do have children and my phone knows it?

Yes and relatively quickly too

Not sure id you’re being tongue in cheek. Anti-natalism (which I just looked up on Wikipedia) seems to have a very long history. All nations and people (with a few cultural exceptions where childbearing is vital to identity) start having fewer kids as wealth and education improves.

I read a book description [0] recently about “anti-memetics” or anti-memes, ideas that don’t want to spread. Stuff like taboo secrets.

Anti-natalism seems anti-memetic because the adherents don’t reproduce enough to carry on these serious philosophies to their belief.

It makes me think about how these ideas end up spreading anyway. So it could be so good that it convinces people. Or there could be false adherents.

There’s some religions that don’t allow sex (eg, Shakers [1]) and it’s curious to me that they still exist since they only grow through converts with each member dying off and rarely reproducing.

Exactly this!
