I feel you. I do a lot of business in Massachusetts, New Hampshire, and Maine. The die hards are unbearable even after last season. They have a play-by-play excuse why they got robbed in the SB.
I am a passive Eagles fan and really don't give a crap, but I can not tell you how many meetings start out about: holding calls, pass interference, and offensive offsides, etc. I couldn't care less. Literally it is an hour of Patriots talk each time in 8 different companies (with the exception of the two Maine outfits. They are Pat's fans but hate people from Massachusetts.)
There is a reason the word "masshole" exists.
