Nah, just outliers.

Everyone hates kids.

Most people like a kid. A kid is cute.

Kids? Nope. Hell no. Ask any k-5 teacher.

I don't believe that for one second. Your comment is in reaction to seeing a c/childfree post once every couple weeks. I know because every angry response in those threads is someone (almost certainly a parent) using those exact words. People barely make hobbies they're actively obsessed with their personalities. People do not make their dislikes into personalities. Sure. Like 100 weirdos ever have. Not worth talking about though, let alone pretending it's everyone who doesn't like kids. I don't like most kids and yet I barely ever even talk about that fact. Literally only ever comes up when some parent (the actual problem) is letting their little shit behave poorly.
