References to slavery in America, even references to movies of freed slaves struggling to free others are generally unwelcome. It’s not something most people want to be faced with when they just came for a simple technical discussion.
I found it clever and I welcome it. The history surrounding slavery isn't a taboo subject, what a ridiculous idea. The commenter in no way is condoning slavery.
Yep, as a black person in the USA… this sort of reads as:
“Remember those times your ancestors were enslaved?
Which relates to a history of segregation and oppression so recent that your parents were alive when it was overturned? You must remember it since it’s still championed by secessionists and is the cause of ever present police brutality.
Remember that? Well wow, do I have a funny joke for you!”
Long story short, there are other jokes that could be made.
Oh no this is totally just my opinion, and I can only defend it with rhetoric, anecdotes, and common sense logic.
Don’t get name wrong, I don’t think the OP meant something malicious and I don’t want to word police in general. It’s just that this joke comes up all the time when Django is mentioned in a crowd. It may have been funny once but now it’s just kind of banal.
References to religions as true are generally unwelcome. It's not something most people want to be faced with when they just came for a simple technical discussion.
