Where would you start with Liverpool fans
Booing the national anthem and showing no respect after they had over 30 years of sympathy and respect every April for Hillsborough = Scum.
Singing pro-IRA songs after the IRA has killed young children over here = Scum.
When Liverpool play away the unfortunate city's that have them have to close their shops and garages to stop them ransacking everything = Scum.
Charging at and killing Juventus supporters who only went to watch a game of football = Scum.
The proud and unwavering support for Suarez immediately after him being found guilty of racism = Scum.
Their fans rocked an ambulance with an injured Utd player inside of it = Scum.
Ashamed of nothing and offended by everything.
That's just off the top of my head
