Exactly. It's ridiculous that teachers are fine with such inconsistent grading on something they (and their graders) are supposed to be experts at -- let alone that they take such joy in leveraging such unhelpful inconsistency against students who objected to them propagating falsehoods!

It reminds me of those "drunk driving costs you $15k" ads, where most of that comes from the expense of navigating the court system (bail, attorney's fees), and the state is somehow proud of this fact.
