Are you REALLY against the softfork ideologically? Question with me for a moment.
I understand where you're coming from, because we're both likely from the early days of Bitcoin.
The philosophical issue I'd like to bring up here is this: Which ethic takes precedence?
Non-alteration of accounts, or adherence to decentralization, anti-censorship, and will of the community?
In this situation, we will have greater freedom as a net total if we lock or banish the SiNMS versus than if we allow this sale. I often favor anarcho-capitalistic ideals, but it can only go so far. At a certain point, we have to be people who are free to fight for our future, instead of machines running immutable code.
Please question your values. My initial view of this situation changed when I remembered my humanity.
