I don't like Biden either, but anyone with half a brain knows there are two choices in the 2020 election. If we had a sane voting system, voting third party might be worth it, but as it stands, no one but you knows your favorite candidate exists and unless you want to become their campaign manager that will still be true in November. Even if you did, and even if you convinced two thirds of the people who would otherwise have voted for Biden to vote for your chosen candidate instead, Trump would still win because half the country voted for him and your guy only got a third. If you vote third party you might as well stay home.
Not voting isn't going to stop the genocide in Gaza. The US will continue to funnel them arms no matter which candidate wins this November. Trump practically campaigns on how much he hates the Jews and he's publicly told Israel to "finish up their war". He'll also make life a living hell for anyone who isn't a straight cisgender male back here at home.
A vote for a candidate is not an endorsement of them or their policies, it's a statement that you like their policies more than the other guy's, and "sticking it to liberals" and "refusing to support genocide" (that's not what voting for Biden is doing, by the way -- a vote for either candidate is a vote for genocide and a vote for neither is an endorsement of both) is not more important than keeping the furthest right politician America has ever seen out of office.
How incredibly privileged do you have to be to see an entire national election as what will happen in the Middle East and ignore Trump's campaign promises to wipe transgender Americans off the map, and further, to not realize that the same thing will happen in the Middle East regardless of which candidate wins?
I hate Biden as much as every other leftist here. But I'll still vote for him because Trump is worse. If there's a single bone in your body that cares about the lives of your trans friends you will too.
People need to understand that it's possible to 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. If you abstain from voting, you are increasing the likelihood of more genocide and if you discourage others from voting, you are an active participant in the overall social apparatus that is probabilistically increasing the amount 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.
Edit: grammar correction
The endgame of your utility calculation is genocidal. 30 years from now, I suspect you'll still be blasting this "vote blue no matter who" nonsense when the choice is between a dem supporting 5 genocides and a repub supporting 10 genocides. You've been anchor biased hard as fuck.
In your hypothetical 30 years in the future scenario, this would still be a "more genocide" and "less genocide" pick. We should never have genocide but there's no way to express that in the US binary voting system, so the choice would have to be tactical.
What do you propose instead?
