|An aside: who was Jim Crow?|
"But what, in Douglass, is a canny rhetorical appeal to well-meaning Protestant reformers will almost certainly be taken by today’s movie audiences as ironclad historical truth. (If you doubt this, just try telling those who’ve seen Django Unchained that 'Mandingo fighting' was not a popular antebellum entertainment but is simply a product of Quentin Tarantino’s notorious imagination.)"This was all after it's release in the USA last autumn. No doubt it will win Oscars but the hype seems senseless, tokenism (did I just say that?!) when it is IMHO - to quote another critic back in the autumn - a 'New Movie, Same Old Skin Game'.
Rambling on: "A racial twist given to what is basically an economic phenomenon. Slavery was not born of racism: rather, racism was the consequence of slavery." (Eric Eustace Williams). Somewhat true although obviously racism has always existed; it is not a black and white issue...no, really, not literally or figuratively. Also,  we must try to avoid thinking 'slavery' was just slavery in the USA or just the Atlantic slave trade; it has involved all colours and creeds, has existed since humans walked the Earth and certainly hasn't gone away.
Update: as matters of interest: 50% or more of the white immigrants to the American colonies in the century and a half before the American Revolution had gone under debt-bondage (indentured servitude) and although there were both black and white indentured servants sentenced to lifetime servitude the first person of African descent to be classed as a slave in what became the USA was owned by...a black man. Additionally indentured servants were often treated more harshly and forced to work more excessively so as to spare the slaves; the latter being 'perpetual property' the former temporary bonded labour.
