It's worthwile to defend offensive speech, like the one in the tweet, because one day there will be a culture/balance shift and what is deemed "offensive" will change. We have to defend what people consider awful now, because they are the low hanging fruit that normalizes the behavior and makes it more palatable to go after less offensive speech later. For the record, I did not downvote you.
