Calling Jews who're combatting holocaust denialism in any form it writhes into the sunlight themselves holocaust denialists because the facts they lay out do not fit your distorted worldview is unto itself a form of holocaust denialism.
The neo-nazis are proud that you're doing the work for them.
Denialism is a deeply loaded word which implies the Holodomor as genocide is fact and scholars who argue against it (the majority) are borderline genocide apologists and are basically lying.
The holocaust is a proven genocide. Nobody is denying proven genocides.
The thing people are doing is pointing out that calling something a genocide when it is absolutely not is dangerous and offensive propaganda literally stemming from the nazis.
You can't be a genocide denier by correctly pointing out something isn't a genocide. If someone says France committed genocide in Britain last week and I say "no they didn't, that's ridiculous" it doesn't make me a genocide denier - because it didn't happen. Genocide deniers are people that deny real genocides everyone else is just stating the literal truth.
