Sure, and vulgarity is also an option. Here's reality: people swear. Some people swear excessively. A good story will rely on whatever it needs to in the telling. If you're dealing with the scum of the criminal underworld, high chances are that they're not going to care if a few choice words harm Shepard's ears.
Thing is, saying it and listening to it was not optional in ME2. And Yep; folks swear, like many of those here that try and get around the filters, and some appear to make my point for me. And I doubt they are the scum of the underworld either.
A good story does not need to rely on profanity, stereotypes, and appealing to the lowest common denominator in language to weave a superior tale. There are enough heroes and villains in literature and film to indicate that other choices can be used well.
While it is common, not everyone uses profanity, and some wish to avoid it. Never have seen Pulp Fiction, Resevoir Dogs, or many other QT films due to this form of speech, or many others like them. Have not invested in The Witcher games for much the same reason. Same goes for books as well.
My choice, and in this case, will avoid the investments of cash and time unless things change, or at least become optional.
