Yeah, the lopsided anger from Boston's fan base is a bit weird. Maybe it's the embedded heartbreak of four decades of spankings the Habs administered to them; maybe it's the 2014 loss to the Habs in the two teams' most recent series. Meanwhile, we Habs fans have other fish to fry. And the Habs themselves have almost nobody left who experienced the rivalry. Aside from Gallagher, all traces of Bruin-hate on the Habs have moved on. Habs are a new roster sailing in uncharted territory with unknown rivalries yet to be discovered.There's no doubt Bruin fans hate the Habs and they will forever but they seem to be the only ones right now holding on to any rivalry between the 2 teams. There really doesn't seem like there's much of a rivalry between the Habs and Bruins on the ice right now.
Also even though there are Hab fans that will forever hate the Bruins it seems it's far less than the hate Bruin fans have towards the Habs. One would just have to read GDT's here and on the Bruins board when these teams play and the hate really comes out in the Bruins GDT and it's quite comical to read but it just seems far less in the Habs GDT right now from Hab fans towards the B's.
The rivalry just needs a couple of upcoming playoff matchups and it will really ramp things up again. The Leafs/Bruins rivalry is far better than what the Habs/Bruins rivalry is right now which is to be expected since they've played 2 recent playoff series and looks like another coming in April.
But yes, I'm sure you're right that the hate is one playoff series away from re-igniting.
