What if slavery still existed? HBO's planned 'Confederate' show draws backlash

The series would focus on an alternative U.S. history in which slavery exists.

But this new fictional tale focuses on an alternate version of American history in which the South successfully seceded from the Union and slavery still existed.

"CONFEDERATE chronicles the events leading to the Third American Civil War. The series takes place in an alternate timeline, where the southern states have successfully seceded from the Union, giving rise to a nation in which slavery remains legal and has evolved into a modern institution," a release from HBO on Medium states.

"@HBO announces drama series CONFEDERATE, created by @GameOfThrones creators/showrunners David Benioff & D.B. Weiss," HBO PR announced on social media.

HBO declined to comment when contacted by ABC News.

Artist Joshua Idehen tweeted about series that have been “green lit” or given the go-ahead in contrast to others that have been shelved or cancelled, like "Underground" on WGN.

He added, "Because what I really want in 2018/19/20 is all the sex and violence of GOT, but slavery."

Others also expressed disdain for the proposal.

"Supergirl" star David Harewood wrote, "Good luck finding black actors for this project."

Here's some of what others posted including Jamelle Bouie, who said the series “could end up amazing or absolutely cringeworthy:”

There were a few that tried to give the premise the benefit of the doubt.
