Long Walk Home is listed as being included with Amazon Prime, but when you go to it, it says "This video is currently unavailable to watch in your location."
The only place I could find it is Pluto. It is now marked. Wish it were streaming on a commercial-free service, but at least it is available. I'm looking forward to it, particularly with your experience of it in mind.
For anyone else interested, here is the Pluto link (strangely, the service doesn't have a search, so it's a challenge to find):

I too am cautiously hopeful that more white people are setting aside the notion that racism is countered with "not seeing color" or being "not racist" and are dedicating themselves to self-examination and becoming more effective and pro-active anti-racists. As Atticus Finch says to Scout:
You never really understand a person until you consider things from his point of view
until you climb in his skin and walk around in it.
And you can't attempt to walk in someone's shoes if you try to pretend you "don't see color" or believe it is only "bad people" who perpetuate racism. We must face reality and seek to understand the full spectrum of the contrasts in the "American Experience" between White Americans and Black Americans, Native Americans, Latin Americans, Asian Americans, and other groups. We need to connect with how traumatic and damaging those experiences are, our own role in the perpetuation of racism, and how urgently things need to change to spare future generations. (Although it is sometimes a useful term, I'm not a great fan of putting people into a single POC bucket. In particular, the "American Experience" for Black Americans and Native Americans over our history create unique, and deeply embedded and damaging structural conditions that must be understood.)
You're probably familiar with these books, but in case not, the ideas conveyed are helping me to find a more proactively "anti-racist" path.
