It leaves you stuck in the system you have along with those players. You can vote third party, organize around a different election system, but don’t shit on people who see that as wasted effort at best and sabotage at worst. They’re not wrong, because it’s an all-or-nothing play. You’re shooting the moon. If you vote third party, you’d better be 100% sure they’re gonna win or you’re just wasting your vote you could have used to cancel a fascist’s vote. Don’t say “they choose not to” but realize you’re demanding they take a huge risk with small chance of success (zero chance if you don’t organize and just complain on the internet)
