The reality is that so many human beings have literally zero emotional outlet, emotional intelligence, emotional IQ (call it what you like) - and football and the widespread excitement gives an opportunity to project all emotion outward. This is fine if the emotion is happy and collaborative. It's not so much fun if it's anger, frustration or anxiety - often fuelled by a shit load of alcohol, drugs or both.
On my thread in the past few days I've seen an ambulance trashed by those celebrating, a girl undergoing a facial operation because of glass thrown during football celebrations. An assault in saffron walden, an assault in Ely. The social club I was in yesterday I overheard the bar lady serving being given a load of verbal abuse. If this is what it's like when we are winning I dread to think what happens when we lose.
As a nation we really need to start asking some questions as to why so many are unable to manage their emotions. Take responsibility for their actions and choices. Own their emotion and not project it onto others or blame something or someone else for their actions.
If you are happy or excited or sad or angry or anxious - these are all feelings that will pass. If you can't manage your feelings without projecting them onto others in a positive way, then get some support.
If you have children then research the meaning of emotional intelligence, learn about it and support them with understanding themselves. And whilst I'm not singling men out here, as girls and woman also need EIQ - don't be tempted into raising boys that are not allowed to cry or be sad or upset. Because they will grow into men that can't process their emotions. And it may be football highs and lows that will be their excuse to project their feelings onto other innocent bystanders.
