That’s not the point. There is not a candidate on the ballot that can win that doesn’t support it.

Which is why the only option for people who actually believe genocide support is non-negotiable is voting Uncommitted.

Joe Biden is not minimizing Israel's genocide, he's actively facilitating it to the maximum extent. There's no way for you to vote Joe Biden and pretend you're the anti-genocide. No amount of rhetorical backflips will change that you're voting for a genocide supporter.

You might not like that hard realization that that is what you are now, but that's what your vote communicates to Democrats; "I accept genocide support as part of the party platform and am willing to go as far to the extreme right as you want, as long as the otherside is slightly more to the right. I'll never revolt."

[...] very real chance of making progress in the future?

There is no progress through a party that supports genocide. None. That's already been established historically. You're essentially voting exactly like a Republican from the 80s-90s, that's your "progress".
