But that's describing the dominant characteristics of those cultures, specifically, the members of those cultures who interact with the human space travelers. That's not describing every last facet of their society. Presumably, Vulcans and Klingons have households, nurseries, farms (or some way of acquiring food), hospitals (or some way of healing), and everything else.Was it? Using Star Trek again, the vulcans were all logical, and the klingons were all warlike. It worked and they got a big franchise out of it. Maybe it would not fly today, but most of it comes down to execution anyway. Neither the vulcans or the klingons make sense for an entire world. No world would have such a lack of diversity and function.
If we translated their characteristics to gods, in a polytheistic pantheon, maybe the Vulcans' head god would be the god of logic and the Klingons' head god would be the god of war, but they wouldn't be the only gods those societies worshipped. Or maybe different segments of their societies would primarily worship different gods. The Klingon warriors might primarily worship the god of war, but Klingon midwives would pray to the goddess of childbirth and Klingon farmers would honor the agricultural gods and Klingon merchants would worship the god of commerce, and so on. We don't meet any Klingons who aren't warriors because the non-warriors aren't the ones the space travelers see. That doesn't mean they don't exist.
