depressing, isn't it... I don't know about racists, exactly. They are like characters in a Billy Bunter story, all unaware that these were popular 80 years ago and dreadfully out of touch with modern Britain. (You can just imagine Bunter calling someone 'sooty' because of the colour of his skin.) And of course they'll claim that the people don't mind it at all, as if they'd go telling the Prince of Wales he's an offensive idiot.
They aren't the only ones:

but as our future leaders, they don't exactly set football crowds a good example.
