Which liberals? All of them? I highly doubt that. The vast majority of political leaders on the left have been highly deferential to health experts. I am sure you can find a stray tweet or two to support your narrative, but show me concrete examples of policy decisions by liberal leaders that were made regarding HCQ due to misinformation about its deadliness. Meanwhile, the Trump administration stockpiled HCQ and caused a run on supplies of the drug based on a flawed study. This put lupus patients at risk of not being able to access necessary medicine.
