Based on what? Plastics like you clearly get more enjoyment attacking Chelsea players/board/manager than from supporting Chelsea.
The media hate Chelsea, if you blindly believe what they say about Chelsea, you will look stupid.
While the song was terrible, and clearly bigoted. I find it equally shocking that the UK is so backward that the cops can arrest you for saying something offensive, a reason to envy the Americans, with the freedom of speech enshrined in law.
