"If I believe that God, or at least my perception of God, is true - why wouldn't I tell my children what I think to be true? "

Exactly. Stop being so disingenuous about what I'm saying. We all tell our children what we THINK to be true. But we should be telling our children that what we THINK is a mixture of our upbringing and the function of the accident of our birth. What you THINK is largely because you were born in the United States of America, which happens to have five percent of the world's population, and because you just happened to have Catholic come-froms. Out there is another ninety-five percent, most of whom are not Catholic and many of whom have either a different version of God to yours or no God at all. As long as you put your version of truth in that context to your children, and encourage them to think outside the rather confined box not of your own making, you are a man of integrity, despite the fact that your faith is basically a huge delusion. From what you tell me, that's exactly what you do, and, believe it or not, I can respect that.
