What do you think are the beliefs, sayings, mindsets, or whatever of this generation that will make YOUR kids embarrassed or exasperated or say "Oh Mom/Dad!"
"To reduce global suffering" yes that's the eco-fascism. Population control is the eugenics equivalent of austerity. You don't get to tell anyone for any reason if they're allowed to have children or not. That's not your call, that's not anyone else's call but the parents'.
Not only is it deeply immoral, like all fascist pseudoscience, it also doesn't work. Just ask China's population control policy how that went.
The modern anti-natalist movement is about the personal choice to not have children, and occasionally being a counsel or advocate for others pondering their life choices. It has nothing to do with government, corporations, or national mythos.
The ecofascism that currently exists is manifest as jingoism against Chinese and Indian (out-group) climate change contributions, which does not take the form of anti-natalist language. It uses tribalist language, as fascism does. The reverse side of this ecofascism is domestic (in-group) anti-anti-natalism, such as Musk espouses. They demand the expendable laborers make more children to weaken labor power, and decry childless individuals as degenerates.
I deal in the real world where shit has consequences.
You say as you stick your head in the sand. You can't accept that the fascists duped you on this, can you? That you're uncritically repeating their talking points?
