In some sense, it is a part of one's identity, for one can't easily separate the worldview from the person. But we enter a strange era when your identity is challenged and remoulded by a non-human entity.
People have always derived a tribal sense of belonging from a set of worldviews, but these views are now perpetuated by robots. These anti-immigration or anti-brown or post-renaissance worldviews are lived by very few people of flesh and blood - it's a set of interlinked concepts and ideals in an imaginary post-truth world.
But it lives more in silicon than in some Aryan ideal. And if you had to draw a line from this silicon to reality, you'd still end up in Crimea or in Pokrovsk, watching a 21st-century battle with echoes of WWI. It is about land and power and politics, like it always has been. But the person fighting "woke" in a comment section over a made-up story about a made-up Disney film doesn't know it.
I'm in India, so the second-order effects of all this are even more surreal here. You get Christians cheering the rise of a Hindutva nationalist government because it's "anti-woke" (only to get heckled and beaten up during Christmas) and Trump supporters doing religious ceremonies for the man for the same reason (only to get the nation's entire suite of exports tariffed), and you see cabs with giant Russia Today ads on their sides in the streets (but the discounted oil we buy from Russia has not dropped prices at the pump by even a rupee). Our lived reality has very little in common with these digital culture wars.
Sorry for the tangent.
I don't think it is a tangent at all, it just underlines the principle in even more stark ways than the other ones do: tribalism is a very powerful button to press and we're in an era now where you can be a 'tribe of one' with your mentality manipulated by extremely personalized targeting to steer you in a particular direction, no matter where you were born or what your original affiliations are.
It will take extreme mental fortitude and some degree of self isolation not to be pulled in. When I was 15 the peer pressure to start smoking, drinking and using drugs was absolutely off the charts. I stopped going to parties, basically. Until I was 13 or 14 or so it was ok and then from one moment to the next it stopped being fun. People don't like being confronted with their own idiocy and just having one reminder in a roomful of people that you're doing something stupid is apparently enough to become really aggressive against that person. Better if it isn't just you, so the first enlist some of your buddies.
That experience really helped me in many ways.
People in large groups are far more stupid than individuals, and the internet has tied people together into all kinds of weird large groups that reinforce their worst belief systems.
