Being my age, most of my peers are Rag fans. When I debate hockey and fandom (Lord Knows I bring the Ranger hate everywhere I go), the one thing I ALWAYS hear is:
"I was a Ranger fan before there was a Devils", and "Who did you like"?
I just tell them the truth, I've always hated on the Rags, and that I was an Islander fan until the Devs came. Then I went with the NJ team. I didn't dump the Isles cold turkey, I followed them as they won their last 2 Cups, but I moved over and have zero allegiance to the Isles.
I tell them I root for the home team, which the Devs are.
