Commenting on Mesic's interview with the Italian media last week in which he spoke also about victims thrown into karst pits (Foibe) in the wake of the Second World War, Radin said on Tuesday that this topic required a more serious approach.
Radin and the Italian Union in Croatia hold that one crime cannot justify another and that it was unacceptable to use the term "revenge" because of the sensitiveness of the topic.
Radin said that many in Istria had experienced Fascist crimes and therefore it is necessary to hold serious and not superficial discussions on the matter.
"Politicians are those who should be engaged in this regard to the smallest extent. Our goal is to overcome that period and depoliticise it in the end," Radin said appealing for the stronger engagement of civil society.
Everybody must admit their mistakes rather than emphasising mistakes of others, he added.
The head of the Italian Union managing board, Maurizio Tremul, spoke about a recent act of vandalism directed against the Italian community's building in Sisan outside Pula.
Tremul said that two weeks ago a group of vandals tried to break into the building and after they failed, they wrote insulting graffiti against local Italians.
In this context, Radin mentioned the cases of Split, Zadar and Porec whee Italian flags and symbols had been damaged recently.
He said he was sorry to say that perpetrators had not yet been found.
