Of course I think maybe what we are seeing is the activist arm of what I've heard called "conspiritainment." It's a way for people to LARP as activists at no real inconvenience to themselves. They get to feel self righteous at no real cost.
It also feels a bit like the domestic version of what I've heard Africans call "white savior tourism" where people from the West go to Africa to fill their Instagram with how they are saving the world.
Picking a real issue usually means confronting and speaking truth to power. That often has real life consequences. Attacking windmills (even literally! that is a thing too!) does not.
Edit: I once heard an investigative journalist and PI make this joke: "How can you tell if a conspiracy theorist is right?" "Check for their name in a missing persons database."
