Some people shouldn't have kids. Especially not those that don't want to have em. Know plenty of people that do that privately and I can respect that.
And then there is the child free movement that is like the vegan movement. Can't go a breath without telling people about it and trying to convert more people.
As a parent that rubs me the wrong way. There are a lot of people missing life experience that a advocate to miss one of the things with a potential for the most profound experience in their lives. Endangering it for others thinking that know it all. Its a little like a Catholic priest advocating against marriage or against sex. Its a topic he can't possibly know anything substantial about because observing is not the same as doing.
