Thank you for writing this. You def raise some interesting points.
I am deep in the childfree community. I write passionately about the topic and I do a lot of advocacy work for childfree people.
I LOVE how you distinguished between childless and childfree. Many people don't even realise there is a difference. Thank you for this.
And you are totally right. Childfree is not a great term. Many of us don't like it. We would love an actual word that isn't centred on the child or not being a parent. So a word without the term "child" or the term "parent" in it. As we are defined by ourselves, not by something we are not, or something we don't have.
But until that word is found ...
