I made no attempt at making a point about parenting. The post I replied to said they wanted to have children for the experience and because their "body was designed to", essentially. The latter is just an appeal to nature. We can choose whether or not to procreate.

Rather, I made the point that I'd love to ask just one parent why they chose to have a child and have the answer not start w/ "Because I wanted..."

Doesn't any question that starts with "why did you choose to do X" expect an answer that starts with "Because I wanted..."?

It is the part that comes after that matters. "Because I wanted someone else to experience the joy I experience every day" is a very different answer than "Because I needed someone to make me feel like I'm important."

Look at what is happening and you see real data and most of the times it makes a lot of sense. Hear people talk about it, explaining their "reasons" and it's suddenly all gibberish.
