I haven't really seen that honestly, it's pretty much a non-event. I have a kid, some of my circle don't plan on it. No one really cares.

I've seen childfree people on the internet complaining about people with kids plenty enough, but I always assumed they were a vocal minority.

The only time I've ever seen this topic as an actual point of contention in real life is people who insist on no kids at weddings. Which I do think is kind of a dick move, but also people's preogerative.
