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?
How is us having children germane to the conversation about protestant ministers time and time again molesting children in their care? Catholics usually don't leave their children with such men, therefore, your logic doesn't follow.
