Had a good mate when I was at college who was a lifelong Arsenal fan, he knew his football inside out. We both of us had a mate who was your classic plastic Man U fan — yes, they’ve always been around — who had literally never set foot in Manchester. We used to just quietly tolerate his football talk, such as it was, and look at each other while counting silently to ten (he was an ok feller on other levels).
I took this gooner friend to Maine Road one time to watch us against them, we went up the steps, took up our spots, we were standing on the Kippax, he took a long appreciative look round the stadium, and just said quietly, “Yes, ok. Big club.”
No problems with Arsenal or their fans, personally. I only have so much energy for hating, because hating properly takes a lot of it and I have less and less of it in life. Rags, then dippers take 90% of what bile I can summon. If you pushed me, I’d say that of London clubs Tottenham fans are revealing themselves to be pretty thoroughly dislikeable. Maybe I should have always known that.
