Can't we all agree that people choose to be infertile?

Wow. What an incredibly rude and bigoted thing to say. God is the one who created us, and God is the one who made some of us have the medical conditions or accidents/injuries that cause infertility. When you say things like this, you are not only hurting the people who do have infertility, you are insulting God and questioning His will and plan for people with infertility. Given that most of the people who adopt have infertility in various forms, you should be glad that God made some people infertile, as a (partial) way of insuring that children who need parents would have more people available/interested in adopting them.
