It's depressing -- but not at all surprising -- how many people here appear to have absolutely no empathy whatsoever for anyone less technical than themselves.
I saw one yesterday: "You'd have to be a moron to <make this tech choice>..."
It would be far more helpful to understand that not everybody knows why it's a bad choice, and teach us.
As usual, there's an xkcd comic that addresses this.
@bwbeach @lauren And that comic is also only a specific instance of the more general rule that when you have a choice between being right and being kind, you should choose being kind.
