Maybe you should show a bit more respect. These guys are having a good time in memory of a mate and that makes them scum?
And people who wear football shirts as 'casual wear' are scum now are they? I just thought they were genuine football supporters who wanted to show an allegiance to their particular club, or maybe even just wear a football top like they would any other top?
Furthermore I think you'll find the term 'gyppo' is not only racist but also extremely disrespectful of another culture, so maybe you should take a look at yourself before you start looking down your nose at others?
