The feeling for the need to defend one's information they present is admirable however, it is only human nature to do so. I have found that it is not necessary as people are going to believe what the wish to believe. Should it be specifics about a badge or opinions of artifacts, collectors ask to hear the truth but when told and it is not what they wanted to hear get a bit annoyed. Having trod that path myself, unfortunately many times, It's simply "Tilting At Windmills". So, collect what you're happy with and do not worry about what othes say.
