They spread this climate alarm to gullible young people, and the resulting anxiety is palpable. Decades ago it was used by selfish people to justify their lack of children; now I don’t doubt some honestly believe they’re doing the Earth a favor by refusing to breed (though I don’t quite understand how having the worst-off people on the Earth as the primary breeders helps anything).
What is even worse is when they crow about having pets instead which they see as being better than children. Sick.
I feel that if they see themselves as so worthless that they should not procreate then I should not bother with their opinions on anything.
