Very possibly.
Don't know about you, but the religious ed I got at school can be summed up as "Here is Christianity in all it's glorious forms," and at the end of the term "and there are a bunch of other religions too".
Quite the opposite, I'm afraid.
Despite attending a supposedly "non-denominational" primary school, we were led in Christian prayer every morning.
In fact, the conditioning and brainwashing worked so well that I can still remember most, if not all of, "The Lord's Prayer."
We were told that God, Jesus and all the rest of that made-up, fantasy, gobbledygook was indisputable fact.
We were also taken to church services at Easter and Christmas.
Then in first year of secondary school, also "non-denominational," a friend and I were reprimanded and told to copy out the European Declaration of Human Rights (I didn't fully appreciate the irony of the punishment at the time) for refusing to ascend the assembly hall stage and accept a "bible" from The Gideons.
We claimed, in front of a couple of hundred pupils and staff, to be atheist.
As you can probably imagine, this went down like a cup of cold sick.
As it happens, we were being a little mischievous because I didn't actually think I was atheist. I was twelve years old and thought I was agnostic.
(In hindsight, I think I was possibly already atheist but simply didn't understand what that meant. It wasn't until a couple of years ago, on this very site, Fluffy pointed out to me that I was actually atheist. He was absolutlely right. :-D)
After the atheist-gideon-situation, I managed to opt out of God-bothering events until switching to another "non-dom" school, halfway through second year. The new school didn't go for the Christianity-down-the-throat approach, thankfully.
