The fact is that you consistently refuse to acknowledge the fact that not all couples can conceive, and that in fact not everyone should have a child, never mind if they don't want a child (which is a good enough reason not to have one in my opinion). It seems not to matter to you that when people have children they can't handle, they tend to abuse or neglect them. So, was it better that they didn't have a child, or that they had a child and abused it? According to your dictum, everyone should have children, but that's simply not the way that God them, and who is to argue with God's design? If he made a person infertile, then it shouldn't be changed, but that person shouldn't be denied marriage, nor should they be divorced by their partner because of their infertility.
If you don't like churches that are open to all seekers, then don't go to one, and don't take your children to one. They can't be preaching to you unless you're attending that church, so if you are there and taking your children there, their confusion is caused by you taking them to that church and then not explaining to them. Shrug.
p.s. I'm not suggesting that Skaloop, or any of the childless/childfree would abuse a child!! Just wanted to clarify that.
