It is, but it's possible to argue somewhat convincingly that the lack of friendliness is in fact due to lack of intelligence. My favorite counterexample was Von Neumann, who didn't really seem to care much about anyone, but then I heard that he actually had somewhat complex political views but simplified them for consumption by the masses. On the whole it seems that intelligent folk really are significantly more moral than the majority of humanity, and this favors the "intelligence implies, or is the same thing as, cosmic goodness" perspective. This sort of argument is also very psychologically appealing to Enlightenment-influenced thinkers, i.e. most modern intellectuals, e.g. young Eliezer.

(Mildly buzzed, apologies for errors.)

(ETA: In case it isn't clear, I'm not arguing that such a perspective is a good one to adopt, I'm just trying to explain how one could feel justified in holding it as a default perspective and feel justified in being skeptical of intuitive non-technical arguments against it. I think constructing such explanations is necessary if one is to feel justified in disagreeing with one's opposition, for the same reason that you shouldn't make a move in chess until you've looked at what moves your opponent is likely to play in response, and then what move you could make in that case, and what moves they might make in response to that, and so on.)
