By the Premier League for one who have now very much changed their sloganising away from Black Lives Matter. Haven't you noticed? If you want political messaging pushed down your throats at every soccer game good for you. Black Lives Matter does not represent a good cause in my opinion. It is creating racial tension not positive race relations. It is a dubious organisation for anyone to offer their support to if you are not a Marxist sympathiser. But maybe you are so it's OK.
