Nothing is anything when you manipulate a definition to exclude what you don't want to include.

Voting is a form of harm reduction, by reducing the damage done by a provably worse candidate. If you meant harm elimination, you're right, but perfect is the enemy of better

Harm reduction voting in 2016 would have prevented the stacking of the courts that led to roe v wade being reversed, along with the naked destruction of our civil rights. Harm reduction voting in 2024 would have prevented the war with Iran, and would have lessened the support that the USA had behind Israel in Gaza. Anybody who says the Democrats would have been just as bad are at best stupid, and at worst, intentionally trying to accelerate a chaotic situation into a worse one in the naive hope that their preferred ideology will come out on top. And any leftist should be politically aware enough to know how that ends up...

Harm reduction is the reduction of harm, ignoring whatever other niche definitions you want to pretend are more important to suit your absurd point right now, which voting generally accomplishes in a vaguely democratic system.
