I just saw a video on instagram which basically portrayed a rich racist southerner using all the same phrases they used to use for slaves, but for their robot.

"We treat this one better because it's a house clanker instead of a field clanker"

"If the clanker acts up it knows that it gets stuck in the box"

It was meant to be funny but definitely highlighted exactly what you are saying.

Yeah, this is why I don't use the word "clanker" myself. I don't like the culture it winks at.

Lol Just watched it minutes ago. Was it this one [1]
