The "real" west wasn't Gunsmoke or Bonanza.
By all accurate historical accounts, Deadwood is the most realistic portrayal of that era ever put into film.
TV Land has some good shows.
...........well, just because bad language and bad behavior was a part of the "real" west, doesn't mean you have to wallow in it at it's worst just to get a sense of it, but you know your need better than I.
Like many, after the second episode I was talking about Deadwood with a friend ("Man, they sure do say f*** a lot"), and he mentioned that writer Milch had done research indicating the level and type of profanity was historically accurate.
I'm not so sure that's true (see Cussing and Fighting Would 1870s cowboys really use such bad words?), as "Jesse Sheidlower, the American editor of the Oxford English Dictionary and the scholar of cussing who wrote The F-Word, says probably not. Not that frontiersmen were genteel."
It's hard to imagine how boring Deadwood might be without the cursing.
