The first black government minister in Italy is the target of racist abuse.

Racism is despicable, and people of good will in Italy should condemn it and use this as an opportunity to examine racism in Italy.

However, prosecuting people for throwing bananas (regardless of who is the target or why) would be an offense against democracy. Bananas are not dangerous weapons. People should not be prosecuted for that way of expressing disapproval, not even when their reasons are despicable.
