> It’s really because statistically, in my experience people without kids are more selfish than those without.

That would certainly be your opinion. I think the ultimate selflessness in a world being more and more damaged by humans would to elect not to perpetuate the species, and help try to leave the world a better place for those who do choose to have kids.

very very bizarre ideology. Glad you arent having kids. thank you for your service.

That's an absurdly selfish position. You're taking a stance that not existing is superior to living in the future, all the while living in the world yourself. Might as well advocate for nuclear genocide.

The flaw in that ideology is that everyone relies on the next generation for care in their old age. Taking advantage of the future generation without contributing to raising it isn't selfless in the slightest.

If you live in a developed country you probably already have a demographic crisis. Not having kids is hurting the next generation, not helping.
