When you're online a lot, it sometimes feels as if everyone's a revolutionary organizer and you betray the cause by not being out on the streets right now doing an uprising.

Bullshit. Global real time mass communication is a very new thing and for the most of history, being part in an uprising, and if, in what role, really was product of circumstance.
Just take care of your people, your neighborhood, etc and you're good. Maybe circumstance will call for a revolutionary act, maybe it'll happen in another place and you won't get to see any of it. Maybe it won't happen at all and you're just gonna continuing to survive and take care of your people during dark times. And maybe you won't.

Anyway, history isn't singular acts of revolutionary heroism, that's just how we tell the stories. It's mostly people taking care of what's in front of them, never to be sung about.
