Have you seen how much beer gets swilled at rugby and cricket matches? Masses. More than that, in fact.
It's not about the booze.
Absolutely old chap, it's a class thing, what? The plebs just can't handle the pop. Read the link, it's not drinking at the game that's the issue, it's about a rise in domestic violence due to the increased general consumption of alcohol during world cup matches at home and in pubs. It's not about football violence, it's about dysfunctional people beating up their spouses.
But don't let that stop you having a pop at football eh. And it most likely is all about the booze because it's a powerful depressant and mood disinhibitor, so you end up with very dark, angry people who lose control easily.
Obviously if people watched rugger and cricket it wouldn't happen because most of them would fall asleep. Ditto the Tour, golf and most tennis 😉
