Well, I maintain that it only sounds coarse because of prejudice. I'm societal prejudice about words that come from the more northern regions because of their closer association with Old English and Old Norse. That's why I object. I'm not saying anyone has to use the word if they don't want to, but I think it's jolly rude to tell others, who do use it, that it's coarse or rude or something you dislike. It's like telling someone you don't like their hairstyle.
Fine. You don't have to like it. But knidly keep you dislike to yourself.
