EA is a hypocrite

OP this is a community run self help tech forum so we are unable to assist with the issue that you have since the majority of us do not work for EA and this is for technical problems with the game.  Also, the game is rated M for mature in the states, PEGI 16 in the UK and 18+ in Germany which is the equivalent to an "R" rating from the motion pictures association.  Since DICE strives for realism in it's games foul language being used by soldiers in combat is a fact - as a combat arms veteran of the Iraq conflict I can personally vouch for the type of lanuage soldiers use in combat especially under fire. 

Since DICE does not have an option to turn off the profanity in BF3, and nor will they add it since BF3's development is over as they are currently working on BF4 you have two options:  you can play BF3 and try to ignore the profanity or you can decide not to play BF3.  If profanity is a hard stopping point for you I recommend that you wait and see if BF4 has the option to turn off the profanity should you wish to purchase that game.
