As an exiled Mancunian in China, I do spread the word to all travelling fans that half and half flags, shirts etc are not acceptable. I point that if they want a game memento, Mary D's do match badges - and a programme is perfect. I ever say take 90 mins of photos, if you need but, never, and I mean never in the strongest terms wear a half and half scarf. In simpler terms, would you put a Japan flag alongside a China flag and walk around Beijing? Their usual reply is pretty much telling me to jog on and jerk my movements back to England. To which, I reply, THAT, that is how we view half and half scarves in Manchester. Outside of Manchester, in Old Trafford it may be accepted as normal but Manchester is and always has been a very tolerant and open city, but these half-hearted, half-meaning scarves are unwelcome.
So to my fellow Blue Mooners, when you find an overseas fans, be welcoming, find out where they have come from - quickly call on Dr Google and Professor Wiki - and whammy, hit them with sound reasoning and a proper excuse. Oh, and make sure they never lift their tainted scarf up. Bag it. Bin it. Kick it out.
