The right response is to ALWAYS react to crying by calming the child, and if the crying was not warranted or necessary, explain that to the child AFTER you have calmed it down.
Children are smart enough to understand sentences like "This is really not something to get upset about", AFTER they have calmed down, and explained in a loving matter.
