you seem to suggest that truth-seeking > tribalism, and we should pity the poor fools who are about tribalism. In this way, you're being tribalist against tribalism, no?
If ignorant tribalism brings people community and happiness, isn't that just as valid and commendable as truth-seeking?
Truth-seeking might provide a level of understanding of the world which is of value to your operating in life. It is not necessarily a sublime good of it's own right. Too much of it will alienate you from your mates.
I'd wager types like you might find on HN, Bay Area, could do with a little less seeking, in fact.
The Underground Man comes to mind, and presents the extreme of this spectrum. But then maybe he'd find mates in an area filled with other Underground Men?
