What's the difference between a pitbull and a black man you remove the chain off the pitbull sometimes
That is a pretty rude thing to say!
I'm saying, it will be best to remove that chain off the dog in order to keep it from hurting you.
It is not nice to make a joke about a black person being chained up as part of someone's property. No human deserves to be labeled as property, and making a joke about something like this is kind of insensitive regardless of what your intention was.
