Hypothetically, if I said "firefax murdered an underage prostitute and then sexually violated the underage prostitute's corpse in 2018 and was never caught, I witnessed it happen and tried to report it but the police refused to even open an investigation, firefax is a dangerous predator and should not be trusted", and you lost your job because of that, should you be the one with the burden to prove that never happened?
We are talking about what is the law in a specific country, not what “should” be the law. Also, the bizarrely graphic description is out of place here.
It's a visceral thought experiment, intended to instill a sense of bewilderment at what being falsely accused actually feels like to someone who seems to offer a normative assertion that privileges bad-faith accusers, without actually causing any of the harm of a real false accusation. That is topically relevant and experientially informative while being restrained enough to not be actually harmful.
