The questions (and the confusion) will never go away. As a matter of fact, it is proof that we love our kids, that we take the responsibility seriously, and that we are constantly being reminded to trust God with our children.
There are things I tolerate that I don't like or agree with. I hate traffic but I know it's necessary in a society with individual car ownership. I dislike the security checkpoints in the airport, but I tolerate them because they serve a greater purpose. I even tolerate the taste of certain foods that are healthy even though they taste nasty (think Kale and beets).
Because of our freedom to choose to believe in something or nothing, which was the God-inspired genius of those men who framed our little governing document called the Constitution, religion has flourished in our democracy. Actually, only one religion has flourished. All the others have had the chance, but none has found the privileged place that Christianity has.
