Profanity has always been a part of our culture...it's just that it was not on television 'back then'.....mostly because they had no television 'back then'.(Milo Farnsworth hadn't been born yet).
But....those who were offended by profanity...usually left when the cussing started.And you can do the same...just turn off the t.v.
Relax...the world is not going to end just because of some T.V. show.
