It's not as bad as in Argentina where Boca's La Doce and River's Los Borrachos del Tablon are basically local mafias. Politicians are always hiring ultras to carry out dirty work for them and provoke violence.
I'm a realist, sure it says on a map that the bit that looks like a shoe stepping in shit is "Italia". It's just like the Russians planting that flag underneath the North Pole, there is nothing there, its just a barren wasteland with some alghi.
