It's just a certain mentality that winning isn't enough. The same mentality that had city players singing about Sean cox (and yes they were and they knew they were) Can't sing a positive song about their own club. Just a mindset. The Argentinians is a classic casual racism that shows where the country in general is at but greatly pumped up by little men in big crowds. The fact that a general level of abuse is fine by a lot of the region just highlights the difference in cultural experience. Our racism is just kept in check a bit more and is just as ugly when it rears up.
