I’m sure this has been explained to you in here already, but just to reiterate…in the current makeup of American politics, abstaining (at least in the key swing states) is effectively the same as casting a vote for Trump. His hardline support isn’t wavering, and hasn’t for eight years now. If Democrats and Independents are unenthusiastic and a lot sit the election out, he wins. If not, he loses. Republican policies if he retakes the White House will make things immeasurably worse for the people of Gaza. To sit out, or vote third party, is to be complicit in worsening their plight.
