Do you have children?
It's not a difficult question and most people would be more forthcoming than you in answering this simple question.
Because you think it relevant doesn't make it so. There is absolutely no good reason to personalize the discussion, whatever you think "most people" would do. I prefer to focus on correcting factual errors.
Whether or not someone has children is very germane to the discussion. Because someone who does not have children is merely talking in hypotheticals, whereas a parent understands what it means to protect their child.
At least all parents should know that.
So, do you have children?
