Why don't some people see the difference between a trend to specific football school and cheering for a specific team! When someone says that Milan played an amazing game against Manure and they dominated, this doesn't mean that he supports/was supporting them, it is all about what school he does prefer and he enjoys. And even if he isn't a Calcio fan, he has an opinion which ought to be respected. Yes and yes...I'm a die-hard Juve fan, but this doesn't mean I must enjoy only Juve.
As far as I read in the past few pages, there are two viewpoints. The first one look at Milan being our biggest rival who should rot in hell and we shouldn't cheer for them or cheer for any team else (They consider enjoying a Milan match in one of their matches cheering for them). On the other hand, people, who don't agree with the previous view, consider watching the match as any other match, but it wasn't like any other match in fact, it was the semi final of the Champions League, a competition which attracts millions of football fans annually. Consequently, enjoying watching yesterday's match wasn't just because we're Calcio fans but because it was a masterpiece in football, and that's all.
