There’s nothing wrong with not wanting kids.

However people should be financially responsible, become independent adults, and have stable careers.

You only have one body so I don’t blame them. If I were a girl I would not want to get pregnant, have my body wrecked permanently, recover from a traumatic birth, and get stuck with a kid either.

Some people are always going to want kids and they’ll have enough to sustain the human race. Don’t get worked up over it.
