Eh, I’d say it is a point worth making to some people even in vague terms. When you’re dealing with people who have been socialized to view everything through an individualist lens of “do your own thing and it will somehow change the world among enough people doing their own thing,” the emphasis alone of arguing for organization can mean something.
You never are in a situation where you can say exactly one word and therefore must pick the imperative “Organize!”, and yet all over the internet we see people saying remarkably little (imo because most of them don’t even know what they mean and therefore can’t explain it). A simple “get involved with a group of activists even if you need to make the group yourself” is much better and should clear up a substantial amount of OP’s confusion.
There are platforms (like twitter) where every word counts. And the TL;DR thing on the internet is real. I don’t think you can blanketly say that elaborating is always easy and therefore it’s always ignorance if someone does not give the full spiel.
I said a sentence, not a full spiel. Literally “apes together strong” is probably a more useful political message than “Organize!”
