Anti natalists are a death cult
The idea is that existence is suffering, and you are subjecting someone to suffer by bringing new life into the world.
"Basically being alive is pointless and sucks"
The fact that anti natalists don't simply KiII themselves proves that this isn't true. They choose to live because living is good actually and life is a gift.
First of all, suffering and hardship isn't necessarily a bad thing. If life had no hardship at all, it would be pointless.
