The NAZIs themselves didn't start with what we say today that "the NAZIs did" - the Holocaust - they started with extreme racism, claiming to represent an entire ethnicity, claiming that said ethnicity was racially superior and a "normal" Genocide along ethnic lines of people from an etnicity they deemed subhuman, just like the Zionists.

You're making the disgusting argument that even when an ethno-Fascist group is displaying massive similarities to the NAZIs at the mid/later point of that ideology, in terms of behavior, discourse and doing a violent mass genocide of people from an ethnicity they deem "human animals", it's improper to compare them to the NAZIs until these newer ethno-Fascists have committed their very own Holocaust.

By your logic we have to wait for the newest version of the same variant of Fascist as NAZIs to take their current Genocide all the way to a Holocaust just like the NAZIs before we can compare them to NAZIs.

PS: What's happening in Gaza was tantamount to what the NAZIs did in the Warsaw Ghetto. I say "was" because the size and nature of the killing and destruction in Gaza has already go far beyond what the NAZIs did in the Warsaw Ghetto.
