Never make your audience wrong (unless, of course, someone is being terribly offensive to you or others). Even if someone’s idea seems a bit bizarre, acknowledge them by saying something like, “That’s an interesting perspective, one I have not considered.” (Be authentic!) And then move on.
There are always other perspectives. Thank others for their distinctive points of view. No matter how many times I facilitate a particular workshop or deliver a familiar presentation, I continue to learn varying perspectives from members of the audience.
