Why are people taking Trump’s disinfectant comments seriously?

Every time you think Donald Trump has lost his talent for making people’s heads explode, he somehow excels himself. His latest? Telling Americans that injecting disinfectant and shining UV light could cure Covid-19 patients. You’ll have seen the clip already, everybody has, but it is worth watching again:

This was a Trumpian masterpiece. I particularly enjoyed the way he turned to the experts for validation, while his mouth trotted out the peculiar ideas. And I find it hilarious, even though I know we are all supposed to be horrified that the US Commander-in-Chief, the leader of the free world, can sound quite so bonkers and incoherent. People might now die, the pundits gravely inform us, from stabbing disinfectant into their veins because they believe every word that comes out of the President’s mouth.
