Racism has been on increase in some countries like never before, there are some countries that if you don't have a particular colour of skin, hair, eyes you can't just enter some places or gathering. This is an unfortunate occurrence.
I think Africans especially black Africans are the most affected by this anomaly.
FIFA, UEFA are taking a drastic measure against whosoever that is guilty of racism in football. We are all one, let all united to discourage racism.
