I agree with your sentiments.
The problem is "tourists" don't understand the situation they're in.
I reckon this happens all the time across big games World Wide - people with money buying tickets and not getting potential consequences
I can't emphasise this enough. I'm not excusing or exonerating anyone. The guy mentioned in the OP was a dickhead. No question.
But we've got to understand what we're dealing with here. Some of these guys — especially the Asians — are on package tours they've paid an arm and a leg for, to the U.K./Europe, they're kind of armchair telly football fans who've maybe never actually attended a real match in their lives, they get a gala match thrown in. They've got literally no idea what football culture is in the U.K., some of them. The tour operator procures the tickets. There's a whole chain involved. The club should pay more attention to this, but then, the club's a business, they probably get a rake-off, and hey, as we're constantly being told, China and Asia generally is the Next Big Thing in terms of markets for the Premier League, isn't it?
The kind of public we're getting is now all sorts. They should be educated, they should be informed. They should be warned. But what's second nature for a match-going fan in England and Europe of ten, twenty, thirty, forty, fifty years standing — we know the rules, we all know them, and we break them knowingly — is not particularly obvious to a charlie who's just rocked up because it's “cool” to say “I was at the Merseyside derby” or “I was at the Manchester—Trafford derby” to the folks back home.
I never attended a sports event when I lived in China, but I'd be very astonished if there's any sort of fighting, anywhere, ever. Because in that place, believe it, you don't just get a stadium ban.
I think the Americans get it a bit more, but even then, the sports culture is different. From what I saw of Latin America, the Latin Americans get it, I think — big time.
