The reasons shouldn't even matter. Child-free people (I use that term to irritate the "kidz-freaks") have a variety of reasons as to why they don't have children and are entititled to them.
These "kidz-freak" bigots are unbelievable. I know the type - these are people who condemn anyone who isn't exactly like they are. "Everybody should be just like meeeeee!"
They're pompous, arrogant, annoying and judgmental and they don't even realize it.
The whole premise of this thread is ridiculous. And I say that as someone who LOVES children, and buys into the "childlessness is killing Europe" argument. But nothing happens in a vacuum. It's childlessness, combined with massive social programs, combined with a huge Islamic immigration problem that's killing Europe.
But I can't see why this is an issue in the US. Why on earth would we want people who don't want children to have them anyway?
