HatTrick Swayze
Just Be Nice
I think the team you dislike the most is directly tied to the time frame you became a devout Ranger fan. For me it will always be the Islanders. What I find fascinating is that having lived in many places throughout the Northeast, the Islanders clearly view the Rangers as their arch rival, so do the Devils and Flyers and to some degree so do the Caps and Penguins. We are the team people love to hate.
This is true. I will add that additionally, having lived in Minneapolis and Chicago there is an odd amount of NYR hate there as well. You will hear a lot more booing and random "F the Rangers" comments than at games vs other non-rival opponents. Leftover anger from the pre-cap days is the best I can come up with.
For me personally, growing up in NJ in the late 90s-early 00s it is the Devils and no one else will ever come close.
