Maybe, but then again, maybe not. Some genealogists have non-genealogy commitments, such as family and employment. Time for a reality check. Then comes the fun of documenting it. More likely they are truly focused on their research.
Genealogists are people and a few are rude.
Just make certain it's not you. No family historian wants to walk into the courthouse just after the most obnoxious genealogist on the planet has left the building. You must be kidding. I've learned a great deal about history, culture, and myself researching my own family. I have two more parents to learn about.
