Conversations with History: Stephen M. Walt 

My undergrad was in history. I disagree that most people don't like history. In fact, I think nearly everyone is interested in history. You can talk to nearly anyone about some era of history. I think that very few are passionate enough to study it at the university level. Also, it's just not the best degree. I think some of the loneliness you feel arises from the fact that so few are at your level of understanding of history. You've studied so much that many things aren't "new" and "undiscovered" whereas an average person would be interested and motivated to learn more; you already know. Also, discussing history is a bit different than discussing other topics. Discussing history can get "preachy" very fast, especially for people at our level or when there's a disparity of understanding, again something you and I often experience. I'm not questioning your intelligence but perhaps your coworkers aren't at your level. I've found that the more intelligent a person is the more open they are to discussing history. Another way to think about is that no one want to be the dumb one in a conversation so these people avoid situations where they might appear dumb. Lastly, don't fall for this normie stuff. We are all individuals. If you can only talk about history then perhaps the problem of with you and not everyone else. Good luck and be proud of your knowledge. It puts you ahead of people in so many ways
