Tell her to read (and you should, to) this book:
I think it gives a nice comparison of the fascist regimes in Italy, Germany, and yes the United States. Comparative history is “sexy” so this should be appealing.
Also, read anything by John T. Flynn. You can find his stuff online for free at Mises. I leaned heavily on him for my brief “Fascist Fraud” chapter on FDR in my forthcoming PIG to Real American Heroes.
