I do not need it to totally go away, nor do I expect it to. The attack just needs to be insignificant. Currently c12% of nodes, c5% of miners, some large VC backed companies and Gavin support Classic. Once this moves down to insignificant levels this will clear the path to a hardfrok to 2MB. Once Classic support among miners is around 2%, I think this should be sufficient to push ahead with a 2MB HF, and I will begin to put more pressure on the Core devs to do implement the 2MB HF then.
People are free to offer a safe HF to 2MB, however the incentive right now is to rally behind the existing rules.
If Classic is resoundingly defeated then I will be far more optimistic about the future, it demonstrates how resilient and robust the system is and I will be more confident the 21m cap is safe.
If there is significant doubt as to which chain is "Bitcoin", then Bitcoin is a failed experiment
Well, firstly, do you not think it as reasonable that a Bitcoin forum wants to focus on one chain and not be used as a tool to split into two and then be a forum for both sides of the chain? People who want the other chain/alt to be Bitcoin can start their own forum. If this is your view then why are you so annoyed about the "censorship"?
The reason another chain also called Bitcoin may be a problem is that it creates mass confusion, if the new chain is regarded as bitcoin by a significant number of people. Hopefully it will be insignificant and not cause problems. But why call it Bitcoin, if not to attack the network?
