Most people are not in a position to choose whether to embrace or reject. An individual is generally in a position to be harmed by or helped by the new thing, based on their role and the time they are alive. Analogies are almost always an excuse to oversimplify. Just defend the thing on its own properties - not the properties of a conceptually similar thing that happened in the past.
