Organic systems fare better when decentralised, that much is true (bacteria are inarguably more successful than man), but the politicisation of media in any direction is dangerous. SMTP didn't try sell you on an ethos.
Social and content silos, our natural tendency to create filter bubbles, and adversarial machine learning 'curating' your experiences and thus effectively, your culture; this is the danger.
Using language like this, and equating Gab with right wing/conservative folks is not going to help anyone. As such it's just another information bubble for people who think alike.
I don't see any empirical data pointing that Humans are tribal by nature in neither of those. The first link just explains the concept, the second is a highly criticised hypothesis.
The article base all its premise on the axiom that we're tribal by nature, and I think while we might all think that makes sense, I've never seen data to indicate we are innately tribal.
I don't know, there's a lot of counter examples in there too. Lots of people jumping ship, immigrating, switching alliance, etc.
There's also examples of multi-tribal membership, like belonging to multiple groups at ounce. Such as your family, your sports team, your city, country, etc, but also things like multi citizenship, mixed race, etc.
You've also got examples of tribes growing massively in size to the point that it's bigger then our social circle. The US is a great example, it's bigger then anyone's social circle, yet people identify at its level and are united within.
I can as easily claim that humans are not inherently tribal, but are inherently lead to organize in ways they believe most beneficial to themselves, which often times leads them to tribes, but not always.
