But then, assuming one's culture is objective while all other cultures are to be studied in their natural state, is frankly a pretension, which also denies its own cultural values and their historical costs--and biases.
Yeah. Again, I don't see it that way. Especially when you're dealing with an entirely new and alien planetary culture.
Essentially the read is, "If they're already warping around space (making interstellar travel viable vs only intra solar system), they're fair game. They've assumed the risk of contact. If they're still planet bound we have no way to predict what problems our sudden appearance will cause. We MIGHT be a beneficial influence or we might, inadvertently, lead to the destruction of an entire species/culture/society just by showing up."
Some criteria had to be established to govern First Contact situations and the Federation chose to use technological development as its primary rubrick. Certainly its a bit chauvinistic but whatever they chose would have expressed some form of cultural bias.
Personally, I think it's a bit simplistic to use that, alone, as a determiner which is part of the reason I gave Riker the same difficulty. In my mind it fits with his earlier aggressive embrace of the Other that he would have a more flexible veiw on the subjet of "cultural maturity" than his bosses back home.
I think the other TITAN authors would agree.
It doesn't mean he doesn't do his best to obey the letter of the law but it does mean he's going to look for any way he can to bend the rule if he thinks it's warranted. And it also means he's going to take any such bending extremely seriously.
