The context of this is unclear -- is the barren poster friends with fecund female? Or is this more the typical Portlandia sneer at those who choose to procreate 1.5 potential ACLU lawyers vs. the 5 to 8 GOP vote-riggers per Red State family? If someone looks down on you for not having children, why are you friends in the first place? And sure, every parent dealing with kids just loves to hear the advice of the child-free, so go on with your bad self, it's not like you're raising anyone who will pay for your entitlements when you're rotting away in a nursing home reading "The Female Eunuch" to the flowers on the wall.
Blah, blah, blah...
I don't have kids, so you judge me on my decision to not have kids. I swear I'm happy with my lonely existence...
Blah, blah, blah...
Go walk your dog and feed your sixty cats and stop complaining. Nobody cares!
