It’s easy to feel like you’re part of an organization that’s operating as a lonely last hold out, because you’re in a dark forest of misinformation and occluded dissent.

Very much this. As was said in Andor:

"Random acts of insurrection are occurring constantly throughout the galaxy. There are whole armies, battalions that have no idea that they’ve already enlisted in the cause.

Remember that the frontier of the Rebellion is everywhere. And even the smallest act of insurrection pushes our lines forward."
