... and I did not dispute that "fact" though I have seen no evidence to support it. If it happened 50 years ago, it was wrong then and remains wrong today. I doubt that it was as wholesale and targeted in the past. I was at university 45 years ago and I recall very little of what you describe.
My fact, supported by current evidence, was completely discounted based on left wing bias against any media that does not support their narrow viewpoint.
What really gets me is that the Labour party, supposedly champions of the working classes, for which I laud them, has now become the puppet of wealthy, privately educated and privileged trendies from London.
