As always, the first targeted will be the core supporters of the movement the coopted, then anyone that seems left wing, then the lgbtq, the probably Latine/native, then probably black Americans.
The Holocaust took many victims, while Jews lost the most, they weren’t the first victims nor the majority of victims.
Many English speakers just use Holocaust to refer to the entire mass industrialized extermination of people, despite it originally being a Jewish word; as that’s how it’s generally presented in media. Hence my comment to remind people the other ~7 million known victims weren’t Jewish. But all of this is good info for those that maybe aren’t up to date on the nearly century old genocide.
As to your last point, it just means we can’t let the fascists live this time. none slightly close to supporting them, anyone in a logistics role, anyone happily voting for them. They can’t be reducated, they can’t be returned to normal society, it’s us or them.
