If I were to put on my conspiratorial hat, this is exactly what those in positions of power want us to be arguing about.
These narratives and the constant fuelling of the outrage fire are constantly pushed by the media and "influencers". I'm not saying that they are somehow complicit in a conspiracy, but more-so looking to make money from the elevated engagement derived from outrage.
As long as we keep fighting amongst each other about various ideological issues, we're never going to make progress on the things posing an existential threat.
