Alex, I think there are a lot of aspects of this issue that are difficult to distill into any kind of simple terms.

As an example...

I was raised in a Protestent denomination. My school allowed the local Catholic Church to use the school for catechism classes after school hours. On my way home, I used to have to walk past the children who were waiting for catechism to start, as they taunted me and shouted to me that I was going to go to hell.

Fortunately for me, I didn't believe them and wasn't too troubled by what they said. And I considered myself lucky that I didn't have to go to catechism. Still, I think it can be safely said that I was infringed upon in some way by that scenario. And not all children in such a scenario come away from that kind experience unscarred.

So how do we insure that these kinds of things don't happen?
