Yes, Mussolini was that batshit:

The war in Ethiopia kindled in the regime a new optimism that Italians could be remoulded into aggressive, well-disciplined and fanatical members of a new master race. Among other things, this meant getting rid of ‘bourgeois’ customs such as the handshake (declared to be ‘soft’ and ‘Anglo-Saxon’ and to be replaced with the Fascist salute) and the formal mode of address, Lei (branded as a ‘foreign import’ with connotations of ‘servility’). Coffee-drinking was condemned as decadent (even more of a lost cause than the other proposed reforms). Mussolini announced his intention of making Italians ‘less nice’ and more ‘odious, tough and implacable: in other words, masters’.
