Here are a few other genocides of the 20th century: the Armenian genocide [1], Porajmos [2], the Rwandan genocide [3].

Please enlighten us on how pointing similarities in the administrative involvement, the systemic nature of the targetting, the harnessing of technology, or the way individuals perpetrating it are made to feel less accountable is, in your words, "highly inappropriate".

I honestly don't see how you could make such a claim for all these examples without negationism.
