When I was a Revolutionary Marxist, we were all in favour of as much immigration as possible. It wasn't because we liked immigrants, but because we didn't like Britain. We saw immigrants - from anywhere - as allies against the staid, settled, conservative society that our country still was at the end of the Sixties. Also, we liked to feel oh, so superior to the bewildered people - usually in the poorest parts of Britain - who found their neighbourhoods suddenly transformed into supposedly 'vibrant communities'. If they dared to express the mildest objections, we called them bigots.
