The progressives that do still belong to the Democratic party (despite your claims) are the only progressives making any serious progress in growing a functional progressive movement outside the party. Your bunch of posers don’t even register in the culture outside of Internet chatrooms where no one else can stand you. It’s the culture that needs to shift, and you are never going to be the ones doing that work.

On the extremely remote chance that a 3rd party ever amounts to anything, it will be because of the work being done by progressives in the Democratic party today. Not just at the national level, but at the state and local level where Democrats are generally a hell of a lot better. (Not what either of us want them to be, but better).

Elections are run at the local level, and there is no third party or independent movements making any gains there at all. The Greens don’t even try. Good luck winning elections when the media flat out ignores you and the people controlling ballot access despise you.
