Is anti-Roma violence becoming mainstream in contemporary Europe?

"Our worst enemy right now is populism... When the pace of economic growth is too slow for too long and fears about the future become too high, we are entering dangerous territory." - Corrado Passero, Italy’s minister of economic development, at recent conference of top European leaders and economists at the French ministry of economics.

Populism is preparing the ground for the violence. Humanity has already learned the lessons of 1930-s in Europe..$1  

While populism may indeed be a problem this does not mean that anti-roma violence is or will become mainstream, this would require a very large shift in public perceptions. In no country in Europe is any form of violence 'mainstream' or popular, discrimination may become so with a resulting increase in violence but it seems unlikely that in any country will violence become accepted practice. Corrado is right to be concerned but this does not mean his comments should be taken the way the debate seems to take them.
