I've got a good joke. What's the difference between a shit-bucket and a black guy? The bucket.
Why would you say this joke? It is offensive.
I just made up the joke.
Comparing black people to poop is wrong and derogatory. Black people are just as much as people as anyone else, they are in no way worse.
What if I said it in an ironic way? Are you an SJW?
I don't have to be a SJW to think saying that is terrible and in bad taste. Its racist and not funny at all.
