From what I've seen, tribalism is core to innate human nature. It's always been there, and until human nature can be edited like a spreadsheet, it always will be.

What's changed now is how visible it's become and how much easier it is to mass organize people and split up into echo chambers that favor a specific viewpoint.

Before, people were not well organized. The internet has been a revolution in spreading views and allowing like minded people to hang out together. Turns out that's not always for the best. But there's no going back. It's only going to get worse until something happens that unites people more than it divides them.
