Robert F. Kennedy Jr.’s latest remarks land at the most volatile intersection of politics, fear, and trust in medicine. When a sitting health secretary suggests that a common over-the-counter painkiller might cause autism — while openly conceding there is no proof — it doesn’t just spark debate; it corrodes confidence in the very systems meant to protect people. Parents already drowning in anxiety are handed a new phantom to fear, while autistic people and their families see their existence reduced to something to be “prevented” at all costs.

Scientists, autism advocates, and former leaders are not merely irritated; they are alarmed. Casual speculation from a private citizen is one thing. Speculation from the person tasked with guiding national health policy is another. Free speech is vital, but so is responsibility. When words from the powerful can change how millions treat pregnancy, pain, and children, evidence is not a luxury — it is a moral obligation.
