So, here's a question: Why is it that some people have strong objections to genealogy/family history?
Yesterday I was google searching for something, and I found someone saying that genealogy is racist. Unfortunately it was one of those things where I wasn't really able to figure out the context because it was part of a long thread that happened to show up on the search, but nevertheless... really? I've also come across people who just view it as smug.
I think some of it is that people are under the mistaken impression that it's a way to prove how great your heritage is or something... while I do think there are some people out there who just want to know if they're descended from a certain famous person, I think most genealogists recognize the unlikelihood of a, proving this for certain, and b, of it even being true. I have found friends who were distantly related to famous people, but given their family settled in the United States relatively early, it wasn't surprising.
Other than that, I can't think of why people get so defensive.
