Joe Biden is “only” Genocide abroad, and probably less of it.
Therefore, a vote for Joe Biden is a Vote against genocide.
No, it doesn’t matter that he’s an active participant in the apparatus that’s creating the genocide, because if he’s in office there’s less genocide. Which is the important part, and pretending otherwise is sophistry. By abstaining from voting, you are increasing the likelihood of more genocide, if you discourage others from voting, you are an active participant in the overall social apparatus that is probabilistically increasing the ammount of genocide.
The utility calculation is dead simple: more votes for Biden in key states makes more genocide less likely, and discouraging people from voting for Biden makes more genocide more likely. Therefore, discouraging people from voting for Biden is a pro-genocide strategy and voting for Biden in battleground states is an anti-genocide strategy. I live in a solid blue state, so I reserve the right to vote third party, but I will also encourage other people to vote for Biden.
You should vote for Biden unless you live in a solid blue state, and even then it’s not a bad idea.
