Waste of everyone's time. There's nothing wrong with "childfree".

"Parenting-free" and "offspring-free" are not the slightest bit better - indeed, offspring is a synonym for child in this case, so it has exactly the same meaning.

I wasn't surprised to discover that you aren't in this category yourself, and yet you want to dictate orders to people who are. "I want to tell you people what you should call yourselves!"

Zero claps. If I could pay for negative claps, I would.
