I make a point of examining my opinions, on virtually everything, daily. When I do reach an opinion, I'm comfortable with it and confident it holds together. I enjoy listening to other opinions, particularly contrary ones, and, rarely, I am sometimes persuaded otherwise. But my opinions are utterly independent of whether someone else values them.
That said, I have a low threshhold for words that seek only to attempt to belittle my, or others', opinions. Because at that point, no one's opinions are being discussed, only posturing. An entirely different interaction then ensues.
As to your story, not knowing anyone involved, 'just point at the picture, jackass' doesn't strike me initially as an insult. I have a lot of casual interactions and insult as a form of humor is common. But then, I wasn't there. If the tone used was hostile or impatient, I expect I'd have a different reaction. Otherwise, I don't think the story is a useful analogy. t doesn't sound like he had faith in, was vested in, or even an opinion, on his meal. If this is a routine occurrence I probably would just tell him to shut up myself and order him eggs. Sunnyside up.
