So this argument is just wrong. The crap some Dems wish for, that people shouldn’t protest Biden’s policies at all or else all will fall is inherently flawed - the US democracy is built on free speech and advocating for change. And when a people are being genocided by a US proxy, many think it is worth it to rock the boat in a safe way.

I fundamentally agree that we should rock the boat and get Biden to change his policies. What I don't agree with is calling Biden, Genocide Joe.

it’s clear Biden could and can do much more to stop the genocide

I also fundamentally agree with this. This is the nuance. Biden has the ability to stop this conflict right now. So we need to pressure him to make that happen. As soon as possible, I should add. I have no doubt Israel's current fascist government will make good on it's threats to attack Rafah at the start of Ramadan. That's the 11th of this month, next Monday afternoon. This is all completely lost with the Genocide Joe nickname.

And if they don’t vote for either because of support for the genocide on both sides, they are not people who care about the country and definitely don’t have well constructed opinions on anything else. (e.g., couldn’t rely on them for a Dem vote if no genocide occurring)

They might reasonably think they shouldn't vote for either candidate, even when they need to be voting for the lesser evil. It's considerably harder to make that distinction when one candidate is Donald Trump and the other is Genocide Joe. We should be making the distinction between the candidates as clear as possible. The last thing I want to here on and after election day this November is that people couldn't tell the difference between Gush and Bore.
