Nobody who is considering having kids is going to actually take any of this seriously so what’s your goal?
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.
It’s either silly memers, or idiots. The whole thing is a giant joke.
