I wish we had more discussion of specific PD episodes. I’m trying to remember the specifics of the OS episode involving the red skinned white hair people who kept on having to feed the dragon cave god thingy. If memory serves there was a big debate around the PD in that episode, but Kirk thought it was better to kill the ‘god’ and free the people from their servitude. What I can’t remember is was the ‘god’ thingy indigenous to the planet or an outsider. If it is the later, then Kirk was actually following the PD by allowing the people to continue in their natural development.
Actually, the one aspect where I’m most conflicted is cases where one group of the society is mistreating another subgroup. In the ST example is easy to say that it is none of our business, but I have a hard time thinking that sounds too much like saying women’s rights really isn’t our concern in places like Afghanistan and Saudi Arabia because its an issue for their own culture to resolve. However, I don’t really believe that because human rights are human rights. Then again do aliens on other planets have an inherent right to human rights?
