Is it bad to support two sports teams at the same time?

I live in the New York Islands and despite the amount of teams nearby me, I’ve never really gotten into sports until a few months ago. I was never really exposed to sports when I was younger for two main reasons: The only member on my mom’s side of my family that watches sports is my grandfather and my father grew up in central New York and is a Buffalo Bills and Buffalo Sabres fan, two teams that only play near me and are on our TVs a few times a year. For the longest time, I’ve seen myself as a Giants/Yankees/Rangers/Knicks fan, but as I said before, I was never really into sports until now. What got me into sports was back in February, when my brother, who’s an Islanders fan, convinced my dad to bring him to an Islanders game. Since the game was during winter break and I knew I’d probably have nothing better to do, I told my dad that he could buy a ticket for me, too. I ended up loving it and definitely want to go to another one.

While I did have a good experience at the game, part of me still supports the Rangers. Last night while I was out, I ran into a friend of mine’s brother. We talked for a few minutes and I asked him why his brother wasn’t where we were. He said he was at a Yankees game, and I told him that I was also a Yankees fan. Then he proceeded to tell me that he didn’t go with his brother because he was a Mets fan. I asked him how he felt about his brother supporting a rival of his favorite team. Then he told me that his brother his actually for both the Yankees and the Mets, describing him as a half-Yankees half-Mets fan. That was when I started to think that maybe I could be a fan of both the Islanders and the Rangers. What do you think? Would some people see me as a confused bandwagon fan and/or not a true fan?
