Casascius and everyone else, I think there is some confusion here. No one is proposing we launch a massive marketing campaign to get Bitcoin to Iran. Even I think that is not a smart move. However, I strongly think we shouldn't be actively reducing the possibility of regular people in Iran to use Bitcoin.
I don't think kicking someone off an internet chat channel is actively reducing the possibility of Iran use of Bitcoin.
In fact I think that translating Bitcoin-Qt to Farsi, LocalBitcoins to Farsi etc, is a noble goal. Just like translating them to all other languages is. I think it's smart to provide the tools for people to use Bitcoin if they wish but actively and publicly encouraging people in Iran to use it is not necessarily a good idea and I understand the risk it might pose.
I didn't see any disagreement with translating it to Farsi, I just saw a well-founded unwillingness to allow it to be discussed in a publicly logged bitcoin developers' chat channel.
