It isn’t an argument, it is more of an accusation.
Selfish? Since when making your own life choices has become somebody else’s business? Why wasn’t I informed? What happens here, is that some people (women mostly) are so jealous about others who ‘got away with murder’ that they just have to shame the free and happy ones.
People who chose to not reproduce not only live their life the way it is right for them, they go against virtually every societal dogma out there plus marketing. They aren’t the ones whose offspring will be destroying the planet further. They aren’t the ones who are insecure. They live happily without the self-destructive need to please their families and societies while sacrificing their own dreams and heartbeats for the vision of others of them. Basically, what we have here, is jealousy of those who never did anything to live their life the way it is right for them towards those who had the courage and confidence to do so.
