About the ballboys I'd say it's not true: maybe he had done it once or twice.
About his ideology it's not a mystery. He was definitely right winged, neo-fascist. I think every ideology is "very questionable": throwing mood on a boy dead in this way is something unacceptable, in my opinion. If you are for "free thinking" you ought to tolerate this.
I've really cried for this tragedy. Luzzi was unique person.
