I supported the fork because it was the rational decision to make under the circumstances. I never invested in the DAO or cared about the investors. The simple fact is that the theft was significant enough to cause an unacceptable and pointless security risk to the network.
Fortunately for us, there was a built-in delay in the DAO contract which provided the foundation and community with enough time to engage in public debate and determine the best solution. That solution was to carefully recover all the funds from the attacker without creating any negative externalities on innocent bystanders. In this sense, it was not a rollback as no other transactions were affected. Consensus was achieved on this goal and the community resolved the situation as expected. Despite all the ignorant comments and trolling, the truth is the HF worked out brilliantly.
The extremists, fundamentalists, and other ideologues who rallied to defend the theft because of their false notion of immutability and demented claims about "bailouts" never came close to understanding the severity of the situation. They never had the moral high ground nor the stronger end of the argument. I'm very pleased they didn't get their way.
In my view, the foundation and community handled the DAO debacle in a responsible, decentralized, open-minded, and respectful manner. I was not turned off in the least by the hard fork decision. In fact, it only strengthened my conviction and trust in the Ethereum project.
