I generally agree with Xabi Gerrard.
People tend to pick their club, or are indoctrinated into a club by family, long before they become politically aware. Where I slightly disagree though, is that this is with all of us for life. Maybe in years gone by it was, but so many 'fans' are fickle these days and simply pick a winning team and often change allegiance to the next winning team when they emerge. Hell, I've known people 'support' a team simply because they like the shirt they wear.
Anyway, that's veering off topic a bit...
I knew I was a Red decades before I had even a remote awareness or interest in politics, but I'm so glad that it turns out that my club sits well with the left-wing leanings it turns out I hold in later life. I got lucky, so don't feel conflicted.
I'm sure there are plenty of Tories that support our club, though. We have fans in all corners, and we have fans from affluent areas of Merseyside too. I'm sure there are a fair few Tories amongst them. I think plenty of people can seperate politics from sport anyway. Personally, I find that a bit more difficult to do. I'd hate to have been brought up to support a club like Chelsea, for instance. Also, if I go abroad I might buy a football shirt from the city I stay in, but I check their general leanings first. For instance, in Krakow I'd never touch Wisla stuff because their fanbase has Fascist leanings which I find repulsive, so I might buy a Cracovia shirt instead. This kind of thing matters to me, but to many, it doesn't.
I think there are more clubs in Europe that link politics and sport, but in the UK I'm not sure there are that many. There are the Glasgow clubs, of course, and you always tend to view Chelsea and Millwall as Right-Wing/Fascist leaning, but apart from that I'm not sure really. Although Liverpool the City and Liverpool the club are seen as Left-Wing, I'm sure there are plenty of Tories within our number given that we are local and national. We are also global, so I assume we'd have a fair number of Right-Wing leaners out there too.
One irony that is not lost on myself and many others is the amount of away supports from desperately deprived and rundown parts of the country who come here and give it large about slums, bins, poverty, unemployment etc before slinking off home and no doubt whinging about the Tories themselves.
Football is so far removed from the game I and many others grew up with. These days it's as though the entire game has embraced Tory values. It's all about greed and revelling in how rich your club is whilst ridiculing clubs that don't have as much wealth. Some clubs and fanbases act just like that Loadsamoney Harry Enfield character. Wannabee Tories seem to be everywhere. We also have players who are quite average but who are multi-millionaires living in mansions and driving Lambo's and Ferraris just a few years after they were out of short trousers. I doubt many of them will be voting Labour in the next election.
