I feel like tribalism is natural (as in, it's the law of nature): our prime concern is the survival of our individual selves. And then of our families. And since we are social creatures, the survival/well-being people around us. And if we're programmed to identify "people who look like me are family", then a tribalism based on appearance is pre-programmed. The next level of programming is "people who think like me and share my values are family"... And the pessimist in me doesn't see how the tribes won't get smaller and more egoistic in this world: population is growing, the melting/burning planet provides less and less resources, and social media is building up the jealousy...
