1: If “sympathizer” is a reach it’s only because “collaborator and ally” is more damning and accurate.

2: And Italy was divided enough over fascism to fight a civil war and have a native resistance when offered a chance, instead of swapping sides when it was clear their preferred side was losing. They still willingly and knowingly enabled the Holocaust, and a war with the Soviets that they knew was both ideologically and racially motivated with plans for extermination and mass slavery.

If you’d like some reading on the topic of their knowing collaboration with the Nazi plans:

I think they do a pretty good job of staying as unbiased as possible in it.

3: It wasn’t an ethnic cleansing, it was a voluntary evacuation.

Though, of course, that half a million people voluntarily evacuated rather than being part of Stalin’s USSR says a lot in itself.
