There are things he should be held to account for

These are Liberal Zionist policies. I'm criticizing him, to "hold him to account" and you are trying to get him out of it by deflecting without argument other than "be normal" Liberal condescension. If he should be held to account, get on the fucking correct side of the line and criticize him instead of defend him.

we should be pushing for him to become a better politician.

We can push the democrats left!!! You have to be an actual baby who did not experience 2016 to present to believe this lie for the umpteenth time. Same shit as Bernie, AOC, Fetternman, etc. Eternal circles that you will eternally justify and defend. Even if this were true though, you are doing the opposite of "pushing Mamdani left" by standing between the left and him and trying to defend him and deflect the left's critiques. You are literally pushing him right, alongside all the forces of capital dragging him right. You are the ratchet in the the ratchet effect, preventing any leftward movement.

Being fucking annoying online and flat out calling him a Zionist is insane

Oh did you get annoyed that a politician was correctly labeled by the policies he enacts? So sorry for you that you had to be annoyed by being reminded this guy took material actions with his power to kill Palestinians and cover up the illegal sale of their land. It's like actions don't matter to you at all, only images and posturing. You are a dog who only responds to tone.

Continues to eat your own. Soon you’ll be by yourself and hungry.

Mamdani is not mine nor have I ever supported him. I do not support Democrats. I'm a communist, not a Liberal or "DeMoCrAtIC sOcIaLiSt". No politician who is part of the fascistic Democrat Party is on the side of the international proletariat. He will become more and more hated, centrist and powerless as time goes on, I will not tie my reputation to him.

The difference between critical support for anti-imperialist nations is that they are actually opposing the US empire, and therefore the zionist coalition. With money and guns and spies they are inflicting damage to the American empire. What is Mamdani doing to weaken the American empire? What has he done to harm the zionists? Social Fascists in the core are rainbow imperialists, they actually aid the empire by giving it ideological cover and pinkwashing it without changing any of the actual power dynamics and material conflict. The AOCs and Bernies and Mamdanis of the world make America stronger, more capable of warmongering and destruction.
