No, good and sincere Christians don't. One has to walk the walk not just talk the talk.
‘even good and sincere Christians get their daughters on birth control at 16.’
Many do not know anything contrary to the birth control argument. They have just accepted things as they are today. They also may not have been Christians very long and still accept the norms of society. No we did not put our girls on birth control. I have young friends who have only been Christians 5 to 6 years and the wife took the shot, whatever it is, and they do not know about BC arguments. They are a strong and growing Christian family in their walk with God in my opinion. Actually, it was learning about this event, that probably caused me to begin thinking deeply about what birth control does to people and how it affects their relationship with God It is just this has come to be accepted, and as I said, in my advancing years, am now learning about both sides. So, like many things in life, you wish sometimes you could go back and start again. I find myself praying for and being more thankful for God’s mercy through Jesus every day. Our role as age advancing adults is to make sure both sides are presented to the BC issue. I intend to do that myself. We have a long way to go to turn back the accepted norms of the past 50-80 years, and it can only be done through persistent teaching.
