When I was a schoolboy, several centuries ago, I was a ward of the Children's Aid. (Technicall, I was a ward of the crown, meaning that effectively the Queen was my guardian -- not that it did me much good.
) I did not know my father -- not even his name -- and he had never seen my face, even as an infant, and my mother was long gone out of my life. Much later in life (in fact not until I was 70) did I learn all the facts, and discover my 16 half brothers and sisters (actually 18 - twins died shortly after being born). My father knocked my mother up and left, and then another girl, giving me a half-brother exactly 6 months younger than me. And then, 4 months before I was born, married a third girl who was already pregnant by him. My mother married a man shortly after I was born who horribly abused me, almost killing me twice, which she did little to stop.
May I just hint at what I might have thought about a "commandment" to honour my father and my mother?
I also did not believe in God. I would not have appreciated being informed "officially" (i.e. on the wall of the school dedicated to my education) that I was wrong, and that there was a God, and I was required to worship Him alone.
Oddly, the commandments do not say that my father shouldn't have left, nor my step-father shouldn't have abused me. God, for some reason, left those out, which rather suggests that they weren't issues for Him. Nothing in God's law against abandoning me, either.
You may think this trivial, and I could just "get over it," but all this happened by the time I was 8 years old in grade 3. You may have heard that these can be quite impressionable years.
Further, I live in one of the most multicultural cities, provinces and country in the world. I was surrounded by Muslims, Jews, Hindus, Protestants, Catholics, Buddhists etc. They were in my classrooms. They had as much right to be there as I did -- and as much right to be respected for who they were, and not to have (for them) "foreign" religious idiologies thrust upon them. School was for learning what a child needs to know -- religion was for home and church/temple/mosque/etc.
If you think I'm making an argument for the sake of it, you might ponder on the things that happened to me -- and why I feel very strongly about it.
