Muricans showed zero interest in football for a long time. Once they started to show a bit of interest in the 80s there was talk that they wanted to change it for murica ... bigger goals, higher scores, razzmatazz, quarters etc. Bugger off!
Now there's money in the game and the murican businesses are suddenly all over the game like a rash. Our national kit is made by a US company, with no tradition in the game, that excels at marketing cheaply uncreatively designed bland wear with its brand logo at stupid costs. They got this particular kit, in a run of bad kits, badly wrong in the eyes of lots of English, whether you think they're over reacting or not.
I'm not really bothered about the flag - it stands for a weak nation broken by the invading Normans and ruled and used cruelly by an aristocracy elite ever since - today pulling strings behind the veneer of democracy. However, I am bothered by what particular brand got it wrong. Bugger off!
