So its ok to offend the deaf.

Today as I watched "Jackie Brown" and heard the ridiculous dubbing over of bad words such as "mothersledder", in order to protect society from such bad words, it occurred to me...What about those who are deaf and have to lip read?.
Should society now cover the lips of those actors in film who utter such bad words with big black fuzzy rectangular blocks so that the feelings of the deaf are protected?. What a country!!! I was always told "sticks and stones will break your bones but names will never hurt you". Quite true I would say.
