Wrongly Unaware

When I read a scientific article on a complicated subject and can't fully understand it, I'm a bit thrown by the clearly uninformed comments from people challenging what they don't understand as if they do--and do so with bad attitudes. This must be terribly frustrating for those who do have the skills to understand.
I imagine it's like an article written by a doctor on a new treatment and seeing in the comments people disagreeing because it doesn't line up with any of the Four Humors or cupping.
