I've seen a few of those before.

Some were CC text from CNN articles with random "war pictures". It was surreal - like a badly done brainwashing video. It had the eerie qualities of belonging as perverse art exhibit.

I have also seen these in "alt"/neonazi/kkk politics channels. There's not much worse than showing pictures of the KKK and black people while a robotic voice throws curse words and racial epithets. There isn't much else to say other than "WAT?"
