EDIT: I think it's prudent to wash vegetables to clean off any herbicides and other chemicals even if they are "known" to be harmless.

Here's a possibility. The scientific social networks consist of people who's research is paid for by the same corporations/government agencies with inherent conflicts of interest.
I only raised a real possibility that is not factored in the two bullet points. Conflict of Interest. We assume that scientists are somehow immune & should not be questioned, particularly when there is evidence contracting their conclusions.
Nothing to do with HN logic. From what it looks like, you are far more of the HN maven than I am...
you're gonna have a real hard time getting all the chemicals off your veggies using dihydrogen monoxide, what with its high boiling point. i suggest using formaldehyde instead.
Or maybe get some veggies that don't have the chemicals on them in the first place?
