All nasty abuse is bad, whether it's about skin colour, your mother or whatever. Let me get that out of the way. Nasty abuse should be dealt with regardless of what it's about. I've always been baffled in sport by the way people can seemingly shout whatever abuse they like at the referee, opposing team or whatever, but as soon as someone says 'black' it suddenly becomes mortally offending. Or if you fly a banner with white lives matter you get permabanned, whilst sportsmen are there with Black Lives Matter. Even though they're supposedly banned from political advertising they're promoting a Communist movement on their shirt for nowt and giving an inherently violent black power salute and an inherently submissive gesture towards blacks - kneeling says you're inferior, you don't kneel to someone you're equal to.
The one thing we should all reflect on is how utterly shallow the masses are. The new fascists will call themselves anti-fascists, forget the name, look at what this mob do. At least 28 people have been killed in BLM riots in America. Most of them shot. Most of them black. It is incredibly divisive and has set back race relations decades. Research BLM beyond it's platitude. They're Communist agitators inspired by a convicted cop killer and militaristic groups like the Black Panthers. Many of the influential people in this movement aren't anti-racist, they're racist and black supremacist.
