Debating etiquette: If you assert that X is “obvious”, “blatantly obvious” or “so fucking obvious you’d have to be an evil, low-status person not to see it” then you are not allowed to provide any arguments or evidence for X unless you first concede that X is not obvious. None of this “Anyone with half a brain can see why X is true, but here’s for paragraphs arguing for X anyway” nonsense.
People who do this are trying to double dip. By claiming their point is obvious they can shame their opponents for being too stupid to understand the plain truth. But since what they’re saying isn’t actually obvious, they layer arguments to make X look more obvious. If X is obvious, you should say “X” and everyone will know you are right. But if you find the need to defend X with arguments, don’t try and shame the people who disagree that X.
