You posted...using bad language is acceptable. My position is clear - never.......that's what sets you apart...your use of the word never......most people accept that whilst bad language should not be used there are instances when the provocation is so great that it is understandable.
I very rarely heard it as a child, and accepted the general opinion that it was unacceptable. I found other ways of making my feelings known. Easy.
From an American point of view, but I agree (don't think they're fundamentalists);
What's Wrong With Swearing?
Swearing Imposes a Personal Penalty
It gives a bad impression
It makes you unpleasant to be with
It endangers your relationships
It's a tool for whiners and complainers
It reduces respect people have for you
It shows you don't have control
It's a sign of a bad attitude
It discloses a lack of character
It's immature
It reflects ignorance
It sets a bad example
Swearing is Bad for Society
It contributes to the decline of civility
It represents the dumbing down of America
It offends more people than you think
It makes others uncomfortable
It is disrespectful of others
It turns discussions into arguments
It can be a sign of hostility
It can lead to violence
Swearing corrupts the English language
It's abrasive, lazy language
It doesn't communicate clearly
It neglects more meaningful words
It lacks imagination
It has lost its effectiveness
