1) racists are not rational
2) you cannot persuade racists, so you should persuade those "neither here nor there" - i.e., those who dispute whether racism exists...? if you need to be "persuaded" that racism doesn't exist in football or society then you're just willfully ignorant. only snowflakes would see people taking the knee to shed light on racism and possibly be offended by it
3) racism clearly exists - and is a form of inciting violence. just watch the Maradona documentary. even if we argue over whether or not hate speech is violent, why on earth should it be permissible in a public arena. should racism be tolerated in school classrooms? in parliamentary debates?
what would be comparable would be hooliganism. hooligans are not rational. how did hooliganism die? the hammer on the head approach.

4) irrational violence can only be met with violence - i.e. morally justified violence
re: Cristina Bicchieri - had a dig around and i do take that argument, positive messaging is always a better method. but i'm not sure to the extent that works with racism in sport. you can't "positive" your way out of people chanting vile slurs.
