Now boffins have discovered that gangs of black youths can cause cancer as well as being, frankly, distasteful.

Docktawh Gillian Keith, speaking from her underground nutrition dome said, "Ever since The deputy commisioner of the Metropolitan Police told me about it, I have been trying to cure reading the works of Karl Marx with a powerful mix of micronutrients, goji berries and spirulina."

She added "As it turns out reading the works of Karl Marx is almost completely identical to cancer, in how it affects the balance of our chakras. And everybody knows that reading the works of Karl Marx is mostly caused by gangs of black youths, who are known to promote a negative orgone balance in the red layer of the energy rainbow."

Of course liberal-minded multiculturalists will no doubt assume that comparing gangs of black youths to carcinogens is "racist", but they can’t deny the simple facts of the case. And the Mail is happy to back Gillian’s words; she gave us a fresh insight into Broken Britain by saying, "Waterboarding is not torture".
