chakka35 I went to RC schools, as did my wife and both my daughters, and I can tell you that at no time were any of us taught that Protestants (and those of other faiths) would burn in hell forever. I can also assure you that none of my brothers or my sister (who went to different RC schools than the ones I attended) were ever taught any such thing.
Now I have no idea who you have spoken to, nor how old they are nor where they went to school, but in RE classes at primary school we were taught that heaven is open to everyone regardless of their faith. I doubt that any school I attended was atypical, so from my experience, that attitude has been around since the late 50's or early 60's.
Times change, as do attitudes. You're more than welcome to believe that RC schools are places where children are indoctrinated, but I, for one, know better.
