I agree that it's helpful to catch yourself feeling that self-righteous buzz. Obviously everyone on all angles of the insanity gets hooked by that feeling. Its also like walking a tightrope, because being internally congruent to your own feelings is fundamental to mental health.
The Cambridge Analytica whistleblower Chris Wylie talks in his book about intensive research being done into how to trigger maximal reactions in audiences by artificially making them feel under threat. The brain's powerful survival mechanism is tripped and you have that explosive reaction that lots of people are probably familiar with to the point of boredom around issues like transgenderism.
That was in 2013/14. The people who manipulate social media in this way have had lots of practise since then. If enough people act out of rage then it looks like something awful is really happening. And the concerted effort being made to weaponise people's emotions against them, like Orwell's 2 Minutes Hate, is concealed.
It's not easy to be true to your own emotional life and those explosions, yet also to gently let it defuse for your own sake when you're ready to. But I do think that if enough people did this then we could get to a point like at the end of The Wizard of Oz, when Oz's disguise has been stripped. But none of that's to say people shouldn't respond and take action, or have feelings.
