@Angel23,
Recall vividly the first 'cuss word' I ever heard on commercial tv. Was an episode of M*A*S*H where some general whose son died called "Hawkeye" a son-of-a-bitch. Since then, commercial tv has allowed more and more profanity. Doesn't seem to be any rhyme or reason to it though. See it at all hours of the day so it isn't restricted to evening hours. Seems to depend most on the channel.
As with exclamations of "Jesus Christ!" context and usage determine whether something's offensive. If as exclamation, most everyone now replaces, bleeps, or otherwise gets rid of it. THis is actually very recent, maybe only a couple years. Seems to suggest Christians are working very hard behind the scenes to get their way.
