Some version of “I see you” will diffuse at least 80% of people who appear to be haters or would-be haters. They’ll even sometimes do an about-face and become your strongest proponents. Just present the facts or wish them luck, and let them come to their own conclusions. I often use something along the lines of, “Thanks for the feedback. I’m always trying to improve. In the meantime, I hope you find what you’re looking for.”
