Well they think that they have the solution to move bitcoin forward, however they way that they try to promote their agenda is by spreading FUD. Like that's going to work somehow. It's a double edged sword and they might cut themselves with that strategy.
I agree, the way things turned out lead many "fanatics" to communities that were supposed to be neutral. As a result places like /r/btc are now extremely one sided and favor a certain hard fork without any wilingfulness to make compromises. Behaviors like that only make bitcoin's image to the outside world worse and slow down progress. I wish that more people from /r/btc would work on proposals and be open to discussion instead of trying character assassination against Core supporters. 24/7
