There are plenty of men who don't care what team you root for. As a Cowboys fan, it's refreshing to talk about other topics other than sports. Sounds like you're surrounding yourself with the same circles. Step out of your comfort zone and don't be obnoxious. I enjoy attending the minors games, not just the majors. If you're into sports and fitness, try a new workout or routine at a different location. Boxing, running, yoga, hiking. These all consist of different types of people. Search for Sox meet-ups. You live in the melting pot of the world. I can assure you there are plenty of legit Sox fans in NYC.

If anything, go to a restaurant or bar/grill with TVs during a Sox game. Friday night 7pm before the alcohol sets in. There you go.
