I have never been to the island of Guernsey. This is a large world and we have a finite amount of time on it and must make our decisions about where we visit based on necessarily limited information. We cannot know everything. I have never been to Japan, for example, because I do not wish to be crushed to death by a mass of jabbering humanity, nor take part in unpleasant sadomasochistic sex acts, nor watch people disembowelling themselves in order to affirm their masculinity.
