Rings my fucking bell, like a perennial fucking plague maiden:
Center harm, not disgust!
When in doubt (and when not in doubt, just swept by problems bigger than you and assured by someone that they know the answer, so don't think right now, just Do!), center harm.
Focus on what specific harm you're reducing with your actions. Make sure it's tangible and concrete. If your actions are minimizing hypothetical harm at the cost of real, tangible harm on others, 9 out 10 times you're on the wrong fucking side, being weaponized by propaganda.
If a conversation revolves around disgust as a driver for action, you're being radicalized. If a call to action depends on your emotional response, you're being manipulated. I'm sorry, this isn't the 90s anymore, social media has eroded the web of respectability of the pre internet society. The primary axis for misinformation to spread in this day and age is emotional response: half the things you believe are true and share as such are not based on fact, expert opinion or personal research. Social media has conditioned us (all of us! You and me and most dangerously of all, the idiots we put in power) that if something feels true, it probably is.
But do you know for sure it is? Do you think it's true because you have first hand experience or actual time spent on reputable sources learning it to be fact? Or just because it aligns with your worldview and it would be nice for you if it were true?
Are you taking action because you're angry and a group of fellow angry folk invited you to join them? Do you have a plan or is this just catharsis? Are you aware of the consequences of your actions or are you drunk on rage and focused only on the immediate future?
Center harm. Center specific actions and their consequences.
Discomfort is not harm. Disgust is not harm. Hypothetical paranoia is not harm.
The reactionary pipeline is real and your self-image as a progressive is not actually enough to save you from falling down the hole. Radicalization is not hinged on politics alone. Saying you're a leftist is worthless if your thought process and actions themselves are indistinguishable from qanon losers. Conspiratorial thought has literally no politics inherently, and your insistence it does is pure lack of critical thought on display.
Center harm, not feelings, not politics, not group think.
Center harm, and remember that individual actions cannot dismantle systemic structures on their own, so anyone who calls for individual action at the cost of community structures is not actually trying to change anything, and instead actively suppressing efforts to make anything better in any way.
