NoKids - just run with analogies, they can only get better!
It's more when it's a written description of people in general that it annoys me. 'X% of British couples are childfree', when you can't know how many made an active choice. I get a bit wound up by the framing of everything as a lifestyle choice.
Also how everything is a community. The skydiving community, the mental health community etc. A lot of the time people aren't referring to a group dedicated to that interest or issue, they just want another way to say pig farmers so say pig farming community.
I write and edit a lot of copy so I'm a bit over invested in clarity...
