No, I don't think so. There are a good many people that I personally know who may not have the scientific know-how to debunk the tales, but think they're too silly to take seriously. The fact that the UFO crowd are vocal doesn't mean they outnumber the non-believers. It simply isn't considered a respectable belief for thinking individuals.
Come to think of it, I can only think of one person I know who falls in the class of true believers, and it's not always easy to tell when she is being serious...
