In one sense, this is the natural outgrowth of the Trump era. Inasmuch as there was a coherent belief that explained his agenda, it was lib-owning — whether that meant hobbling NATO, declining to disavow the QAnon conspiracy theory, floating the prospect of a fifth head on Mt. Rushmore (his, naturally), or using federal resources to combat the New York Times’ “1619 Project.”
But in a post-Trump America, to “own the libs” is less an identifiable act or set of policy goals than an ethos, a way of life, even a civic religion.
I get the impression that the goal is just to get on YouTube or Instagram and get lots of views.
