Vocal participation in a genocidal system is endorsement of it. You can't tell people to vote for one of the parties of Capital one year and then suddenly tell people that actually it needs to be overthrown and think that's going to happen 5 years later.
At some point you have to commit to it being "broken" (actually working as intended of course) and organize based entirely on the fact that it is and can not be supported in any way whatsoever. We're long past that point with the "lesser evil" party currently committing genocide.
Successful revolutions in the past have used elections primarily as a way to show the size of the movement, never by endorsing a party of Capital.
Organize. Endorsing a genocidal party won't stop them from committing genocide.
