> The end of protests and a society that works better for everybody, yes.
You don't actually bring that society to the table. That's outside of your power. If anything, you promise that this society will somehow come about if only your demands are met. Kind of like the politicians that might promise almost anything, if only you elected them.
> Progressive candidates, like members of the DSA and politicians they endorse. One thing that has come out of these protests is a rise in progressive candidates, both running at all, and actually winning some primaries. The progressive candidate who won the primary for my state House seat over the long-time Dem incumbent chose to run after the Floyd murder.
Sure, but that only happened because these progressives were compatible with voter behavior. Show me the successful progressive Democrat who also supports completely abolishing all prisons. Well, maybe in Portland.
> The protests themselves have moved the overton window.
Have they really? In the public perception, these protests were against police brutality, which virtually everyone is sympathetic with. If the protests had been perceived as being in favor of dismantling the criminal justice system, virtually nobody would've supported that.
> A single recent example is how public support for protesting athletes has changed.
Supporting or not supporting someone's right to protest has been inside the overton window all along. What hasn't been within the overton window would be a position like "protesting athletes should be imprisoned" or "athletes should all be forced to attend a protest".
Similarly, defunding the police is within the overton window, but abolishing policing outright is not.
