That depends, is Johnny wearing a Madrid jersey?
Nah I'm joking, but yeah, I understand your viewpoint. Some Barca fans don't hate Madrid (or at least not enough to consider this) and that's okay, it doesn't make them less of a Barca fan or anything. Just personally I respectfully disagree, after all the bad blood over the years (not just in football, but outside of it as well) I don't want to see Barca hand the title over to Madrid. It's not even really about what their fans would say, they're only fans - but just the idea of it sickens me.
I mean I was bitter about the whole Everton-City thing because it affected a team I love, but I understand why their fans would want that. Also the Lazio fans who celebrated their own loss several years ago so Roma couldn't win the title (perhaps an even more accurate comparison). When I first got interested in football, I didn't understand this mentality either, but over the years I've grown and don't blame fans for feeling that way about their rivals - and even agree with it when it's my club with the "power" to do so. Especially Barca-Madrid, because like others have said that's a rivalry beyond football.
Again, don't take what I've said as an attack on your opinion. Everyone is free to say what they believe is right, whether it means screwing Madrid or sticking 100% to the rule book. Also, I'm going to say that I don't condone anyone at the club paying the referee to throw the match, since someone brought that up. I don't want to see us doing anything that's actually illegal.
