it depends how to person says it and if they think that they agree with their jokes, if they just say something racist but try to defend yourself by saying that it is a joke, it will not help because you're basically looking like you just think racism is a joke (which it isn't), but if the person brings it sensibly as a joke, it might be a bit confusing but the right words should be use. If a person does a joke about drugs or death, they should show signs that they do not actually think what they're saying is actually true, this can also be referred as sarcasm

TL;DR: try not to do those, or just choose the right words, a poorly-choosen word in one of their jokes, it is going to look bad on them
