Well, in fairness to the OP, that's not how it started out. I read it more of a "Everyone else loves to babble endlessly about their kids, can I talk about how I love not having kids with others who choose to not have kids?" Yes, it went quickly downhill from there, but in no small part to parents who too it as (if I read them correctly), were somehow put out by the OP's desire for posting his thing.
I don't really have a dog in this fight, as I don't feel the same need to talk about my decision to not have kids, but there was a sharp turn in the direction this thread went that was not entirely the fault of OP.
