You're right! The alternative would be no different, though. And voting for a third party (or just not voting) basically does nothing, and makes it more likely for the actual fascists to gain power.
It sucks that Biden is so cozy with Israel, and it also sucks that there's very little we can do to change it right now. But giving up entirely and letting actual fascists gain more power because of one issue is so incredibly short sighted it borders on insanity.
You want change? You'll find it easier at lower levels of government, at state and local levels. Those changes will make it easier to change things at higher levels.
It also sucks that it takes time for effective change. But that change will never come if you just give up.
