Sure, genuine racism should be fought, I'm with that. Those morons who racially abused Saka and Rashford on social media - give then lifetime bans, get the police involved, whatever.
They should publish all details of all incidents, not just selected ones to prove the problem, so we can see how many and what proportion are genuine incidents and how many are fake. Because I wouldn't be at all surprised if BLM types were some of those sending them. Often activism has a habit of making adherents become the perpetrators when they want to amplify the problem they face in a misguided way.
Also, what a stupid approach it all is. If you were being bullied as a kid, what is the one thing you wouldn't do? Let people know that something bothered you ...
When instead you publicly bemoan the mean words you show that it bothers you and then what are people going to use?
People use words to hurt, and will use whatever words they think hurt most, usually the most obvious. If they want to insult someone who's fat, they don't call them stupid, they reference the most obvious physical attribute that they are likely most sensitive about.
So announcing what insults you the most to the world ... what do people expect the response will be?
