As is often the case, you only need to be stabbed once. Better to have it and not need it rather than to need it and not have it.How many blacks have been stabbed in London over the years, and how many by "white supremacists" ? As long as they stay in the right post code, they may be ok without a stab vest.
Black people and non-gammons have known it for years, that black people can be targeted for no other reason than being black. Thanks to recent publicity, people like Hate and many other blinkered Daily Wail reading gammons, are finding out for the first time too.
