Advocating against voting for Democrats, no matter what the particular language, is advocating for actions that will increase the chances of Trump getting elected, of Republicans having majorities and of Israel's further escalation in Palestine, in addition to all the other bad things Republicans will do.

The time to move Democrats on the issues is not now. Those times were during the primaries (in which I voted uncommitted on the presidential level and for pro-palestinian candidates on other levels) and after the election through things like lobbying.

If there are particular third-party candidates who have any reasonable chance of winning rather than being a spoiler (I don't know of any), it's reasonable to advocate to their electorate that one vote for them instead of the Democratic candidate. However, if one supports Palestinians and opposes genocide, the best vote in the presidential election and in most national or state elections on November 5 is for the Democratic candidate. That's not a "vote blue no matter who" opinion or an "all you need to do is vote for the Dems" opinion. It's harm reduction in the short term so that we can ensure that there actually are medium and long terms for as many people as possible.
