Never mind football. Become a rugby fan instead.
I'm a Glasgow Warriors fan in the Celtic League (teams from Scotland, Ireland, and Wales), but I've also got a soft spot for Bath from the English Premiership. The best thing about rugby though are the international games. Something that's not really a viable option in most Northern American sports on a regular basis, though with rugby it's the main event. There's the 6 nations tournament (Northern Hemisphere) and the Tri Nations (Southern Hemisphere), and the world cup every 4 years. The British and Irish Lions tours every other four years in between, and the constant "friendly" games played between everyone.
Plus rugby has a much more friendly atmosphere around it. There is a great belief in the rules and code of conduct in the game, and the referees and officials recieve much more respect. The fans themselves view the sport differently. With football in Europe/South America there is often such bad feeling between differing fans of opposite teams. Living in Glasgow, Scotland, I unfortunately see this al too often as there are two teams called Rangers and Celtic, of which the fans generally hate each other. What's even more pathetic is that the hate is based upon religious bigotory as the fans of either team are historically either Protestant or Catholic respectivelly. The fans are segregated and don't mingle, there is always problems with violence and drunkeness, and it's nothing more than a past-time with which to distract the great unwashed of the city.
I've never seen any similar problems at rugby. I can happily go to a Scotland v England game in either country and the fans are mixed together, before, during, and after the game without incident. Everyone can enjoy the game as the sport and entertainment it is. A Scotland or England fan sitting in amongst the opposition supporters at a football game would have to do so in fear of their life!
