I'm from New England. Lifelong Sox fan, and less so Patriots fan.
Patriots videotaping scandal bothered me, but I was able to put it in context that it wasn't a load bearing beam in their dynasty. I did become less of a fan.
But the fact two back-to-back teams employed this cheating methods and won the World Series makes it impossible to discount as a crucial factor.
Both World Series championships absolutely should be reversed. Every player who participated should be suspended for a year.
I haven't lived in New England for over 25 years, so it's easyish for me to say this, but upon reflection I think this plus the Patriots cheating scandals have led me to the decision to sever my fandom. Hard because for many years I was a passionate Sox zealot. But this stuff matters to me, and because people chose to cheat, they stole dreams from others who were more deserving. I find this detestable to the point of their being villains.
I cannot support a team that did this. I'm out, and shopping for new teams to support.
