I love football, it is my favorite sport by far and Formula 1 doesn't come near. I am also a great, passionate fan but that doesn't mean I fit the European stereotype (drunk, likes to fight, ignorant...).
I wouldn't get in a fight because of someone who is ignorant enough to first: try to pick a fight with me; second: try to do so by talking about sports.
The real fans don't get into situations that would hurt their team's image, a real fan cheers for the team, and despite them doing badly sometimes, they still cheer with hopes things will get better. And they also don't act like senseless ignorant stupid people and boo their players for whatever reason (yes, there are players who don't deserve much support, but that doesn't mean they aren't human and can't make mistakes).
one example:
Adriano played for Flamengo when he was younger than what I am now. Since his first game, I had faith in him. Well, he scored 2 beautiful goals and was a one-man show! He also went through rough times, as everyone does, but especially for being a teenager you have to understand he was still learning the game, different styles of play, and above all, would make mistakes.
Well, my team has the biggest fan base in the world, and when you are that big you have more chances of having stupid "fans." The kid was targeted at every chance possible, and the result was a guy who wouldn't want to leave the place that he loves but must do so because he just can't stand anymore. Result? He flourished into one of the top strikers in the world, making millions of dollars, and he is worth an incredible amount of money for his team, instead of the ridiculous 6 million dollars paid for him 4 years ago. Above all, he is happy and is supported by the fans. The Flamengo fans suffer because they lost a great player, and even though it was the fault of a diminute number of fans, it was enough. I blame those ignorant supporters for how football goes in my country.
And back to the point... what makes it even better is the possibility of emulating your idol, and taking part in the same sport, whereas in F1 only a very, very small number of fans can get into a car and drive to fulfill their dreams and emulating their idols.
Above all, doesn't matter what you like or dislike, it gives you no right to talk so much garbage about it.
