You are certainly welcome to read anything you like into my post, but, yu would be wrong in thinking that I was saying that God is punishing you individually for the crimes of a nation, it is not just you who is unable to have as many children as you would want, it is rampant nationwide, including my wife and I.
Read your Bible, starting in Genesis and see how God will deal with many if not all in a nation that has spit in His face.
So explain why your God doesn’t make infertile the populations in Islamic countries or those of Islamic immigrants?
