The problem with football is that unlike Rugby, Cricket etc it is the most inclusive sport in the country. You can barely have a pot to piss in or you can have a 4 bed in Sussex and a holiday home in Cornwall, it's just open to everybody. And that's why these incidents happen so often because football holds a magnifying glass over society. It's an issue within the game and the institutions involved need to do all they can to eradicate it, but the simple fact is that if you are seeing sexism, racism, homophobia in football, then it's highlighting a wider issue within society and really it should be an alarm bell for government to dismantle. Unfortunately the current government are made up by people who literally deny the existence of systemic racism, and the previous opposition quite literally, alongside our current government, defined the words systemic racism, when he was the head of a political institution that allowed and encouraged anti-semitism.
Football can only do so much and I think we are going round in circles expecting tangible change within society when within the last 4 or 5 years society has become worse for it, especially after Brexit, the persistent racism used within it's campaigning and by large chunks of it's supporters.
