This isn't being blown out of proportion in anyway what so ever. Abusing somebody racially, mentally or physically is disgusting and ought to be punished and I'd say that the punishment these idiots have received his only too lenient.
As to the incident you're referring to Stan, have you ever seen any footage of the attack? I ask because this racial case has received a lot of publicity because there is video footage on the internet, accessible all over the world and the culprits can be clearly identified, I'm sure the event you witnessed would be as widely publicised under the same circumstances.
I am sorry but I don't think it would if you google Athens 2007 champions league final liverpool,fans you will see the fans accounts but it never made the bbc news whereas this incident is never off it. I watched it on the news tonight they pushed him off the train and called him names I see worse incidents in our town centres every Saturday yes there is the racial dimension which quite rightly elevates it but that it what elevates it not the incident and I am pretty sure the victim did well out of it compensation wise. I am not saying this is not noteworthy but no one was murdered or assualted some perspective is needed
