How right you are, McGrath - and I think the more the young ones see of the world the more they become familiar with its diversity.
With the Boy Scouts we had no class limits, and we greeted the foreign scouts as they were: white, black, yellow, brown and so on - all brethren. Here we learned to respect the foreigners in their ways and learned a lot of and about them, could teach them something, too.
This attitude helped me a lot when travelling in three continents. Wherever I have been, I first looked for scouts and firemen with whome I have more in common than with my fellow countrymen of the big travel agencies (mostly bad manners abroad).
So my advice to fight racism, jingoism, intolerance &c. is to accomodate the young as soon as possible to the diversity of the world and its people. Give them good literature about this theme. In English literature I remember the Merchant of Venice, where the Jew deplores his fate in a subdued minority: Is his blood not as red as that of the majority &c.? Isn't he a human being, too? Very strong text.
