Often, when older movies and shows get put on streaming services and other platforms, they get parts redacted, taking away from the original value and artistic intent of the piece as to not 'hurt' people's feelings or to push an agenda (most of the time, the latter). You cannot purchase these films legally anymore without them being censored, and as tapes and DVDs degrade, the content is lost to time.

The Nazis burned books to censor ideas and remove history. Disney redacts parts of films to hide ideologies that go against theirs and to censor the past. They're not the only organization that has committed the crime of deliberate and systematic concealment of history; this is happening everywhere. We are losing media that cannot be brought back after the fading archive of our memories is gone.

“Where they burn books, they will burn people too in the end.”
— Heinrich Heine

I have a 35mm scan of The Song of the South in its original theatre release and racist glory. Disney pretends it never existed.

That is awesome man
