Racism isn’t confined to sports, it’s prevalent everywhere, some countries much more than others. The key is education, the effects racism can have on people can be demoralising. Children in schools need to be educated on it, diversity must be preached. It might be hard to change the ways of older people but we can make a change by educating the young on this matter.
Racial discrimination cuts across every sector. It happens at work place, worship places, government houses and almost every organisations. That of football seems to be more evident because the whole world is watching at the same time. I actually don't know the origin of racism but I believe it is connected to ignorance and illiteracy.
I think that rasicsm problem in football isn't such big as it was 20-30 years ago. Back things were really terrible. Now it still exists and I doubt it will extinct anytime soon. But I think it's not systematic problem, it's not that all 50k people in stadium is making monkey sounds or something similar, usually it's few people in whole stadium who is acting stupid. And unfortunately, our society is full of stupid people
With the emergence of many laws and rules about racism. I believe it will gradually fade in coming years or decades. In football racial abuse can happen to anyone. I was surprised when it happened to Saka and Rashford.
