The meta-fallacy of committing a fallacy simply because you've decided that logic doesn't apply to you, your argument, or your preferred conclusions. It's the rhetorical equivalent of playing chess and declaring that your pieces can move however you want because you've decided the rules are arbitrary. The arbitrary fallacy encompasses all other fallacies, but with the added twist that the person committing it knows they're being illogical and simply doesn't care. They've decided that their truth is truer than your facts, their logic is logicaler than your logic, and no amount of reasoning will change their mind because reasoning is just, like, your opinion, man.
Example: "He committed the arbitrary fallacy in every debate. When presented with evidence, he said evidence was unreliable. When presented with logic, he said logic was a Western construct. When asked what he would accept, he said 'common sense,' which meant whatever he already believed. There was no way to win, because he had declared the game rigged and was playing by his own rules, which changed constantly."

Get the Arbitrary Fallacy mug.The meta-fallacy where one side is forced to prove every assertion, back every claim, and satisfy every demand for evidence, while the other side can simply move goalposts, demand new sources, dismiss evidence as insufficient, and never provide anything themselves. The arbitrary burden of proof is the debate equivalent of one person carrying a piano while the other skips ahead, occasionally turning around to complain that the piano-carrier isn't keeping up. It's how conspiracy theorists can demand that scientists prove negatives (prove that vaccines don't cause autism, prove that the moon landing wasn't fake), while offering no proof for their own claims and dismissing any evidence against them as part of the conspiracy.
Example: "She was trapped under an arbitrary burden of proof. Every time she provided a source, he moved the sourcepost. Every time she met his standard, he raised it. After two hours, she'd provided twenty sources, and he'd provided zero. When she asked what he believed, he said 'I'm just asking questions.' The questions were infinite, the answers were never enough, and the burden was hers alone."
