I think there is a tendency to see what you grew up with as normal. It makes it easier to see the weird in other countries.
But as someone who grew up in Florida, I had no knowledge of "creationism" and religion wasn't allowed to be taught in a state school. I believe when creationism is discussed it is to be taught as a theory alongside evolution much like in RE which every child does in the UK does no matter which school they go to. You know there's an obligation for every school to teach RE and that it should have a high percentage (higher than any other) of Christianity?
My children and I live in the UK and in their Catholic school they have learned all about the Bible, how Jesus is real, and he died and was reborn etc. All learned as fact.
1/3 of schools here are religious. They learn fairy tales as fact. Daily.
In this first world country, 1/3 of schools are propped up by religion and people have no choice but to send their children or home educate.
Does it occur to people that in America we have these arguments because religion isn't allowed in schools, not because it already is?
Where is the uproar that your children are being taught that Jesus did magic 2000 years ago and are spoon fed a religion that leads to all of this shit?
