Just because something already exists, doesn’t mean it can’t be also caused by something else. Like canser. It already exists. But smoking can cause it too.

Next to that, it’s paracetamol. It predates the discovery/naming of autism. It’s already proven not to be the cause by other studies. Of course these studies could have been wrong, but I highly doubt that.

So this statement is incorrect. Doesn’t change the fact that I don’t believe a word of either Trump or RFK. I still believe science and I still don’t believe pseudoscience.
