Summarizing the Iran debate
Hamelin's site first attracted my attention for its postings on atheism and transhumanism, which I think he does a very good job of defending. I find what I consider his rather hard-left politics considerably less appealing. I think his approach to questions such as the Iranian nuclear threat is far too fixated on abstract "moral" algorithms rooted in some unreal Platonic universe, and blind to the pragmatic considerations necessary to deal with the real world. Yet I have to say that he is one of the most ethical debaters I've seen on the internet, always going out of his way to treat opposing views fairly.
Update: Here's one last exchange. But that's the end of it as far as I'm concerned.
