Notes:

inb4 someone thinks I'm a fascist, no I am not. Not even close. I'm just comparing how simplistic Mussolini's views of race were compared to Hitler's, who seemed in some cases obsessed with it.

While researching on anything else about what Mussolini had said about this subject, I only found him being concerned about birthrates and demographics, which is pretty normal for today. While he did call Slavs (in this case Croats) "a barbaric race" he did a few years after WW1 which kept pretty much the entire Italian population thinking about them in a similar way because of the war crimes committed by the Austro-Hungarian army in Italy.
Exept that, nothing in particular, he even had a Jewish mistress when he was in power.

Hitler was a whole different game on this subject lol
