It's not a religion, it's reality and acknowledging that we can't always get what we want when we want, and sometimes, the best option is harm reduction. You're going on and on, like voting is always about ideological purity, but it's not. The current system we have means you can push as far in whatever direction you want during the primary elections, but when it comes down to the general election, there are two viable candidates. The reality is, most third party slates, don't even have a path to 270 electoral votes. Of the two that do, only the Libertarian Party has ever received an electoral vote, and that was in 1972 because of a "faithless elector," rather than support at the ballot box. The Green Party? They only show up every four years to make perfect the enemy of better. They're not serious. That leaves you with Trump and Harris. If we characterize them as cynically as you seem to view them, the choice is between someone that impulsive, vindictive, transactional, and devoid of even being able to pretend to a modicum of empathy, versus someone that isn't stopping genocide fast enough. Of those two, which one do you think is more likely to exacerbate genocide the most?

Saying you're not going to vote for a candidate that "allows genocide," doesn't mean genocide isn't going to happen, it just means you get to feel better about yourself rather than inching things toward less genocide that might actually save some lives. So take how you will feel about yourself voting for someone that "allows genocide," and set that aside, and ask yourself, out of the two, who is going to make it worse and who will make it less worse — because that vote has real life-and-death consequences.
