After reading your responses to what I have posted in the N-Word,the Quebec/French Canadian threads, and seeing your new avatar pic, I'm concerned about how your children, if not your family, would take this sort of thing.
If what you said about using the J-word to your wife is true, I suggest that you stop using the word immediately. This sort of language is not what your kids should hear or at least experience through some other means. Actions do speak louder than words. I have experienced some of this conduct in my childhood through my father. Trust me, it was not pretty.
