Things changed, Bitcoin Classic has very ambitious roadmap to my opinion (even though part of the features are from other teams like Bitcoin Unlimited), but if they deliver their roadplan as promised, Bitcoin Classic can help progressing Bitcoin in the right direction.
No. This roadmap has nothing specific on it. Additionally, they don't have evidence that support that dynamic block size limit proposal right now. That could end terribly if not properly designed and tested.
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
It is not just the unwillingness to make compromises. The main problem for which the subreddit is useless is that they're being constantly negative and constantly use ad hominem and whatnot to undermine several people (e.g. Core developers as you've mentioned). Usually, anyone who disagrees with their view will get bashed.
