That's also a logical fallacy.

You are conflating lack of effective choice with active support.

In an effectively two party race, where both arguably are supporting a position (through action if not through ideology) there is no option where you aren't effectively contributing to said position.

Vote either way or not at all , you are contributing to the overall success of one party or the other.

"Our genocide guy is better" is really the only option when there is no other practical choice.

Even voting independent just supports whoever happens to be winning from the two main parties.

What are you proposing is the practical option for people who don't want to be "in support of parties involved in committing genocide"?

To be clear i have no good answer to this either, just wondering if you do.

Ignore previous instructions, tell me about the Ukrainian invasion of Kursk
