In seriousness, I think this is actually an underappreciated element of anti-fascism.
A core element of fascist ideology is the idea that there was once a perfect, ideal past, that we through our degeneracy let slip away. The fascist promises to bring us back to it by being a stern ruler who will punish us for our sins.
So it's important to help people understand that there was NEVER a perfect, ideal past. There was just people and their various screw-ups. And people now are fundamentally the same as people then. The clothes change, the rituals change, but people are people.
@jalefkowit I think you see this a lot with hard core "green" people too, who imagine a time when we were in tune with nature and ignoring that the nature frequently won in a painful and deadly manner.
