Terminally unserious understanding of history and scale, the comparison in-and-of-itself trivializes the Holocaust
Denying a thing that happened
You can stop there
Trivializing the Holocaust by equating it to other events is an agreed-upon definition of Holocaust denial by a fairly broad range of institutions and viewpoints. Take from that what you will, but please don’t engage in Holocaust denial by pressing this point further. Unless you’re a Nazi, in which case I can’t really fault you for being consistent.
