I mean a group of people can talk about a common belief and explore some of the concepts further.

It might be those that are antinatalist want to feel that they are sharing their beliefs with others that feel the same way. Maybe it doesn’t have to be a message for those having kids but a way to feel accepted for believing that there are too many humans already and we could really do with a fuckton less.

The planet is on its way towards an extinction event and we are driving it. Some people chose not to want anything to do with children.

Maybe, just maybe, someone on the fence will realize that nothing they can do will offset the carbon debt and damage that bringing another human into the world will do. And then maybe, just maybe they will decide not to be some “fuck you I got mine” shithead.

Birth rates are dropping across the globe.

You can’t stop someone who is determined, but you can create situations where it’s inconvenient. I.e. birth control gives people choices as to when it’s good to have a baby, equality in the workforce gives people a better use of their time then having a baby, lack of basic and affordable childcare and healthcare makes it very expensive to have a baby.

Antinatalism is winning. Maybe it wasn’t a big conspiracy, but it’s happening.

It’s either silly memers, or idiots. The whole thing is a giant joke.
