They're just here trolling. The only good Nazi is a dead Nazi. Israel's finance minister said they intend to "entirely destroy" Gaza, and the English language has a word for "something you entirely destroy by fire": it's 'holocaust'.
So, I think we should trigger this guy more by using the term in the original, objective sense:
This genocide, to which all current supporters of the Zionist state of Israel are party, is intentionally making a holocaust of Gaza.
ETA: Let the record reflect that the denial of any genocide when shown such irrefutable evidence, --- whether the Holocaust against Poles, Jews and others of the 40s, or this genocide of Palestinians --- makes you party to its crimes.
