I'm not implying anything, I'm offering a recitation of what modern neuroscience and psychology have discovered about the way in which the minds works. Yes, of course you can voluntarily choose to regulate the content of your speech but the more extensively you have assimilated yourself to a particular form or manner of vernacular expression, the greater the probability that you will unintentionally have instances of slippage, of the Freudian variant. Take this anecdote for whatever its worthy but I used to spend a great deal of time fraternizing with a white power type militia organization whereby our discourse would consist of denigrating the niggers and deploring the jews. After sufficient exposure to and immersion in this sort of "hateful" rhetoric, I found it extremely easy to inadvertently incorporate the word "nigger" in to my conventional, daily vocabulary repertoire. Q.E.D., the more you hear, speak, type, say it with intent, the more likely you will do so unintentionally.
