Thorne,

You might prefer to regard yourself as a realist, but what you display is cynicism.

You're right that "we" try to suggest that people "we" disagree with are brainwashing their audience, but that's just "us" propagandizing. The mainstream Christian Churches do not try to prevent contact with other sects or religions, nor do they condemn them. Admittedly, some bigots in Ireland and Scotland still object to contacts between Catholic/Protestant communities, but this is on historical-political grounds rather than religious ones, and is not condoned in any way by the mainstream churches (and, for clarity's sake, I do not regard the either Free Church of Scotland or the Free Presbyterian Church of Ulster as mainstream).

All schools that I know of here, including Roman Catholic and Church of England schools teach their pupils about all the major faiths, although they obviously follow their own particular forms of worship in school assemblies and the like.

And that is as it should be.
