There are some on some ballots, but you cannot fill out a ballot anywhere in America without casting a vote for a person who supports genocide. You can choose not to vote, but that's not participating in the process.
To someone who isn't American, I can understand how alarming and unfathomable this might seem, but I am telling you the truth. What you see on TV and social media is not representative of what most Americans experience at the ballot box.
I'm not just searching for them, I'm canvassing and donating to them, but there simply aren't progressive options in every race in every district. And even some nominally progressive candidates will support genocide if it is politically expedient. Politics is the slow boring of hard boards, and one of those boards right now is global human rights, and we're not even halfway through it. You get through with constant pressure and effort. You can't always get what you want.
