To say there are still problems doesn't mean there isn't significant progress. Otherwise, there is no significant progress anywhere in anything.
> what should have happened in response to metoo and George Floyd/BLM was action that went beyond symbolism.
There was and is:
Laws have been passed in many places protecting rights. Oppressive systems like bail have been reformed in many places. Progressive prosecutors were elected around the country - some still are in office. Even the other prosecutors have (often) stopped backing law enforcement corruption. In some places, police have been prosecuted and jailed for the first time.
I think people overlook it for a common reason: Many things that were disruptive change then became the norm, so people don't notice them. As they say about innovation: First they laugh at you (ridicule your idea), then they say it's not in the Bible (violates the established orthodoxy), then they say they knew it all along. :)
> And the GOP had DC tear apart the last visual reminder, the Black Lives Matter road mural [2] under extortionist threats.
Maybe the last reminder in DC, which I doubt. I see plenty of BLM signs (and LGTBQ+ pride flags) in cities.
