I think those parents who teach their kids they must believe in God or else they'll burn in hell are not doing it solely for the sake of abusing their kids. They just think they're doing what it is best for their kids. I think saying indoctrinating kids is child abuse is a bit of a generalization.
Now, if the parents punish their kids for not believing in their religion or not believing in God at all, that's going to be fruitless because it would only make the kid hate his parents.
Either way, parents who do those things aren't the brightest.
I just had a discussion on FB (and it's still on going) with someone about this. Their position as a parent is that they're teaching what they believe is right to their children.
What I failed to get across in very clear language was, it is completely acceptable to raise the children you see as best fit. What I wanted to know is do they feel it's acceptable to state that one specific faith or upbringing is correct? Do they teach their children this is what they believe in and WHY, or just cause that's how they were raised?
I made the point that most people are religioius because of their parents made them. If you were born in India, there's a good chance you'd be Hindu. If you were born in the Pakistan, you'd be a muslim. And of course if you were born here in the USA, odds are you're a christian.
It really has nothing to do with the word of a religious book that has caused religion to spread, and then take a firm hold on the land where it's popular. It has more to do with people in positions of policital power that dictate what you believe in. Had Emperor Constantine not declaured Christianity the offical religion of Roman Empire, would that have altered the course of that religion through the western world? Had certain Mullah's not gained control of parts of the Middle East, would the religion of Islam still be practiced the way it is today (which IMO, is barbaric in most of those countries).
So while a lot of people would like to believe it was the power of words from those prophets, it was really more powerful of politicians enforcing their views on the general public.
Luckily most of us do live in a society where you are free to believe or not. But I don't feel it is right to give such a narrow minded viewpoint to children. You can raise them a Catholic, but should you completely ignore the other faiths or ideas of a non believer or secularist? Would it be better for the child to gain an understanding of right and wrong, and then let them figure it out on their own when old enough to comprehend?
I don't know, it's a sensitive subject. I don't have kids, I never will, so I can see how it's hard to take my opinion seriously when I don't have that perspective. I just think we should be fair to children when it comes to matters of faith. Tell them Jesus is love, and that helping others is the right thing to do. But if they ask questions about the rest of society, don't jump into that easy position of saying "well, those people are wrong". They're not wrong, they just more times than not did not have a choice in what they believe.
