I'm new here, but I'll give this a shot because this topic is very personal for me.
I think your question, which boils down to 'why do FANS think the media/refs are pro-Wings?' can be answered very simply: homerism.
My best friend is a devout Sabres fan, and quite knowledgeable about finer points of the game, but her homer blinders are super-glued to her head when it comes to believing that the refs, the NHL, the media, and even the concession vendors are out to get her team (in all fairness to her, I think the infamous No Goal gave every Sabs fan a persecution complex-- it's not paranoia if they really ARE out to getcha!
I've seen her beliefs about bias against [insert teeam here] repeated all over the 'net for every NHL team's fanbase-- even here, a little bit, especially about the Versus announcers being anti-Wing tools in Games 1 & 2 (I personally can't say, don't get Vs myself, watch on CBC or listen to RW radio-- BTW, it was just horrendous last night, not being able to see what happened. I'm so glad that I came across this site last week and was able to follow your GDT posts here. Bless you... but I digress).
I think that some kind of protective instinct kicks in when media/refs don't seem to share an often unconditional love for one's team-- as in: Well, if they're not praising us/calling things our way, they must be AGAINST us-- those hosers!!
Anyway, that's my take...... oh s***e, Sens just scored AGAIN... if it's a sweep, SabreFriend'll be bitchin' and moanin' for the next five years..... sheesh, Ottawa, throw 'er a bone, willya ever?
