Lmao, you are Schrodinger's Liberal - both a liberal and not a liberal, until the moment you are observed
I don't care if you are one or not. I care that your utilitarian perspective on 'minimizing genocide' heavily skews toward a desired electoral outcome irrespective of the actual platform. You can insist all you want that you believe genocide is a huge problem and that you agree that democrats are complicit, but if at the end of the day your interpretation of others' behavior is being guided by the one action that quite literally can't effect whether genocide happens or not, then to me you're a liberal in the only way that really matters. You are standing in the way of liberation by gatekeeping acceptable forms of protest and criticism that fall outside or antagonize your preferred liberal institutions. God forbid someone be critical of democratic governance that falls short of the radical change that is required to avert catastrophe because they, themselves, have decided to preserve the liberal institutions that created the problems in the first place. You thought people were being uncharitable to Biden's accomplishments because your judgement of him seems to reflect some arbitrary scale and you assume it's what everyone else must be using.
The only other way of illuminating the problem with liberalism is to point out just how much the 'liberal party' resists changing their policy toward Israel, despite the majority of americans holding negative views on Israel, their war crimes in Gaza, and our continued blanket support for them. Even Sanders and AOC took more than a year and a half to recognize it as a genocide. The primary feature of liberalism that I'm concerned with is it's prioritization of protecting liberal institutions over addressing the harm and exploitation those institutions are responsible for. Israel being our flagship ally for influence and control over the ME is why liberals (democrats, republicans, and even most progressives) are willing to overlook, ignore, justify, or outright defend the atrocities that happen in the name of preserving that geopolitical cornerstone. That includes people like yourself who care about it in abstract but limit your view on acceptable action to what does or does not work inside our electoral institutions. I don't care about preserving Israel as an ally - my ideological framework prioritizes liberation politics, not the preservation of liberal institutions. If a liberal institution is responsible for supporting oppressive regimes and genocide, i think that institution should be dismantled, which means that how or if someone chooses to vote is less important to me in achieving that goal than what football team they follow. That is what informs my self image as a leftist. Complain all you want if you think that line of criticism is unfair or ignores what you think is more important, I don't care.
The more you try justifying your perspective in utilitarian terms the clearer it becomes that any alignment you might think we have is paper thin.
