Yeah, I know what you mean but this concept is not so easy to adopt for me as I grew up in an environment based on what we call here "clubism". That basically means that in football, for example, you support only your hometown club and only the national team of your own country. But to be honest, I have developed some affection for other national teams as well, especially those of countries where I lived. But I still wouldn´t call myself fan of those teams. Here in my region, being a fan means being a hardcore fan :D
