Completely agree with most of your post. However, your complaining about Rooney hating Scousers and singing them sort of chants. Then aren't most footballing fans the same. I've been bought up hating Burnley and i'll admit that I do, i've also joined in the same chants that are anti-Burnley. Does that make us all similar to Rooney?
It's only natural that someone dislike/hates their rivals. Ask most Rovers fans and they'll say the same, they hate Burnley.
