I agree that that we do need something like a collective action platform so people can coordinate much better than they currently do. Also something that you didn’t directly mention but I think you imply is that there doesn’t need to be complete agreement before action is taken because there are alot of valid disagreements on how to move forward but there are also alot of agreements as well that are ignored in public conversation because we take those points as a default.
I’ve been working on something similar to this on my own time (which you can see in my post history) but honestly we won’t move forward if we don’t actively start working together properly.
