The US primaries and the general election are two different things. Voting uncommitted in the primary expresses support for the Palestinian plight and does not give Republicans any ground.
The uncommitted movement presents a safe and effective avenue for voters to voice dissatisfaction with President Biden’s policies, particularly with the Israel-Hamas conflict. By doing so in the primary, voters can signal discontent without risking a Republican victory in the general election. The purpose is to send a wake-up call to the Biden administration that it is failing to address issues and effectively engage with the party, vis a vis that Biden is enabling a genocide.
That being said, anyone who calls for an uncommitted or third-party vote in the general election i will personally kick in the gender neutral balls (in Minecraft).
You could take that to mean that Ukraine is committing genocide against the Russians because they are "destroying a national group in part" by "killing members of the group." Literally any warfare would be defined as genocide under this. It's utterly meaningless and needs to be better defined.
