I'm not a top-20 regular here, but I've read my share. And yes, agreed, there's a big difference between "he's gone, he's not on my team, so I don't care - he's just another player in the league", vs "Fuck him, I hope he loses every game". The former is a totally reasonable thing to feel, but the latter is grist for stereotyping and insulting the Pats' fanbase as spoiled and ungrateful, and I thought it was a chimera. I guess there are at least two here.
Per your insistence, I went back and looked through the last 15 pages of threads, and found only two polls that were even tangentially on the subject, both of them right around the time Brady left in March 2020.
The Sting 2020: asked the extent to which people here could root for the Bucs in 2020. Didn't really get at the question of "I don't care" vs "fuck him". Almost nobody in 70 posts expressed an active dislike; Oppo in post #30 said "I will be rooting for the Bucs to go 0-16 and the Pats to go 16-0", and then
elaborated in #62, but that was it for the actively-rooting-against crowd.
And then
The Decision 2020, a poll from Dec 2019 about how people would feel if Brady
did leave. There weren't options for "will root against him", and the poll and discussion were mostly about a potential future for him on the Pats, rather than on how they'd feel if he left.
There was
Gone Brady Gone, a lengthy non-poll reaction thread to the Brady departure decision. Those rooting for him to fail were
this guy,
@drbretto was initlally
jilted (and elaborated / doubled down, and got a raft of shit for it, including
from you) but may have come around to neutral, and... that's it, at least for the first 5 pages. Everyone else was in varying stages of shock, but those with composure wished him well.
So if there've been threads-upon-threads taking BBTL's temperature on Tom Brady since his departure, you're gonna have to link me to them, because I feel like I put in a good-faith effort here to hunt - and I found exactly 1 lurker who was rooting against him as of a month after his departure.
