Your's is the typical defense of genocide-enabling Zionists and their allies from feddit.org in defense of Isn'treal: "The Holocaust was different! How dare you compare it to the Armenian genocide, or the Rohingya genocide or what is happening today in Gaza?"

A genocide is a genocide. It already implies mass.

Genocide was coined to mean, and is generally used in law to mean, the destruction of an ethnic group as such (as a group). This is the case whether it is done by killing of all members of the group or other means, such as dispersing the group. In common usage, genocide is often used to mean “systematic mass killing”, whether or not the purpose is the destruction of a group or something else, such as terrorizing the group or killing a population without regard to group membership, more specifically known as democide.
