As someone heavily involved in 's presidential campaign, I can say that OP's position is much closer to the official campaign than people disagreeing. By that I mean we are not particularly interested in how people vote, but in using the campaign to reach people and engage them in politics outside the electoral. Our campaign is a vehicle to big swathes of desperate and disconnected people who think of politics in purely electoral terms - whether that's that we have to vote for the lesser of two evils or that the failure of voting to fix societal issues means there is no path forward.
We know that when we go out and canvass, we're going to interact almost entirely with people who are not ideologically committed leftists. The phase of organizing in the US demands that our work be focused on finding and bringing in people who are not aware of the necessity or existence of a vanguard working class party and convince them that their vote is only an extremely small part of their potential political engagement and the general path to fixing this rotten country.
Therefore, we always have to approach people empathetically, understanding their position so that we can move them towards revolutionary socialist politics. That requires us not to denounce Kamala voters as Hitlerites in training.
