Conte returned to Serie A this season and was struck by the difference in attitude.
“Racism is a problem in Italy, but so is any kind of insult, and after three years away, I find Italy has regressed," said Conte in a Press conference ahead of tonight's Milan Derby.
“People write exclusively to foment hatred. Italy has become far worse lately and we are all to blame. We're talking about something that educates the next generation to hate and engage in violence."
He added: “It would be wonderful to see fans attend games just to cheer on their own team. Children ought to hear that instead of observing these hostile atmospheres that are right on the borderline."
