We should indeed keep an eye out for the defunding of medical research but as even a few quick numbers from the NIH (at least speaking for the US) show, it hasn't generally been getting less funding year over year right up to the latest numbers. All the opposite actually. Increases in funding have shrunk slightly, but that's not the same as defunding.
Similar stats apply almost globally in any relevant public funding context. After all, if there's one thing that everyone wants, from rich to poor, powerful or weak, it's to hedge against bad health and a shorter lifespan by whatever means available, and especially if those means involve throwing money that isn't even yours personally at something with publicity.. Even the most selfish politicians can usually get that through the fog of their self-interest.
Yes, the autism+Tylenol thing is infuriating, but there are nobler ways to express that opinion.
