Actually the script writer is trying to establish how uncivilized Deadwood was at that point in history and how rapidly it changed. If HBO gives him enough seasons the intention of the show is to DRAMATICALLY clean up the language and look.

I like your sense of humor.

Just quoting the producer of the show. That's why he picked that town and that time in that town's history. Civilation came to Deadwood fast and hard. If you want to show an area getting civilized the first thing you have to do is show it as very uncivilized, basic dramatic techniques.
