Well, how do you justify shutting your country up from other countries and peoples though? It's generally not easy without some sort of idea of racial purity/superiority.
It's even more difficult to imagine how on an individual level you could be ideologically "fascist" without being racist. Does Di Canio just somebody who thinks 'This has nothing to do with any other country, but our government is so awesome, so fuck our individual rights and lets give it undisputed authority?' That's probably even more screwed up than Racism
