Meh, I don't 'support' anyone as such in International tournaments. Until the knock-outs, most International tournaments aren't worth a **** and bore the living **** out of me anyways. But it's good to have some 'interest' in someone if you are to watch. (Normally Italy for me as it's a Country I've always been fascinated by. Shrugs.).
'Morally wrong' ..... Interesting POV. The short answer for me would be if you came from this City, and had years and years of being looked down on by the rest of the Country, and had your City down trodden by successive Governments growing up; you'd have a better appreciation of saying 'F THAT!' when those same people expect everyone to come together and support the Nation when it comes to football. Then you can take that wider and even if I were England inclined, as a fan I'm polarised again as everything is geared toward the Southern based England fan with most every game at Wembley. Try getting back North on a Wednesday night from there! And that's not to say a lot of people here won't be keenly following England next month. They will. I just personally have no interest for the above reasons that get a lot deeper when you get into it. I don't wish England to lose. I just aren't arsed if they do. Just nonplussed and uninterested either way.
International footie bores me most the time. There's just little I can get out of England that I don't get out of my own club in Europe. I've seen most every top player live. Been to too many different Country's and stadiums to mention watching my team. You look around the average England game and it's all little clubs and provincial towns. England trips for them are like European trips for me that they'll never get the opportunity to be on and experience outside of following England. And the insular, xenophobic. 'little Englander' neanderthal 'fan' that still blights the National side I'd rather not be associated with anyways but that's another story.
Why does Liverpool seem to be unique in this viewpoint despite it being true for almost any northern city and town? You can be patriotic and anti-government.
