Actually, a death toll any larger than "6 million Jews" is considered antisemitic.
Jews get upset if you try being "one of those annoying people" who try to take from them "their" holocaust and try redefining it as the deliberate persecution of so and so many non-combatants by the Axis powers and their collaborators.
Here's an article by the times of israel where they express their low-key anger at the silly notion of the holocaust having anything to do with any goyim suffering: https://www.timesofisrael.com/remember- ... istorians/
Remember, the Nazis euthanizing their own fellow Germans is already a separate event (Aktion T4), and the persecution of the Gypsies is, I believe, referred to as "Porajmos". This way the Jews have repeatedly made sure the holocaust is ONLY about their suffering.
