I was one of the first people in here to support Kamala. You can check the record. Check the election thread. I was pushing for Kamala while most of these Johnny Come Lately Libs/Centrists were still humping Biden's corpse. But it was plainly obvious to me that you cannot make a strong argument against the potential of a future Trump administration endangering the Palestinian cause when you're actively aiding and abetting their genocide right now. Kamala ran a campaign that was incredibly hostile to the Palestinian cause, which was both an immoral position for her to take and electoral malpractice. At no point in time did she even attempt to show she credibly shared the perspective of the anti-genocide coalition or that she could be reasoned with. Time after time she treated anti-genocide groups like lepers. All in the service of reaching out to heartless moderate Republicans with the acquiescence of brainless Liberals. If she wouldn't even give the Palestinian cause space at the DNC, why would we believe she would give it space within her administration? She ended up continued the same mistake Biden did; making people of conscience have to step over the mutilated bodies of Palestinian children to vote for her. Some couldn't stomach it. That's not their fault, that's hers. When a politician puts people in some Joker-esque trolley problem, you can't be surprised when they lose votes.
I'm not sure what irrational anger you're referring to, but the political party that lost opened that door themselves by also excusing and encouraging the genocide. There was no anti-genocide option on the ballot. Yet for some reason, many people in here reflexively, instinctively look to blame the relatively powerless nameless individual voter instead of the actual powerful politicians and Party that could have changed the losing dynamic but chose not to. The urge to lick boots is deeply ensconced in the Liberal mindset. "My political leaders are never capable of failing us, it's us who is capable of failing them."
