Its understandable that you wouldnt want to expose your lads to it, but unfortunately, these things still go on. Not sure what you can do about it though. Either you collectively tackle it head on, or you inform the authorities. One has a physical risk and the other may not be effective anyway. Strangely enough, I saw a couple of these lads over in Anderlecht. Now, I didnt know they were part of the Happy Als lot at the time, but they were on the same flight as me and we got chatting. Seemed like nice, polite lads. Saw them later, outside the stadium, singing some absolute s**** about Liverpool being white, etc. I was pretty shocked. One of them even said hello to me. It was only after Lisbon and the Arsenal game that I found out they had become quite notorious for it.
