>You can absolutely think it as long as it stops there.

If that's the attitude it renders virtually every discussion about the topic moot and the people in question better stop trying to give life advice to anyone else.

My wife and I don't want kids and we've heard our fair share of (unsolicited) opinions on the topic from people who clearly weren't always happy. I've only ever known one woman I worked with, who was a brilliant scientist, tell me straight up she regrets having children and wished she could have focused on her research.

If that's not something you can honestly say without being berated then clearly the 'propaganda' still works mostly in one direction.
