I feel like I just watched an infomercial.
So being that most curse words are used to belittle others, then if I'm talking to someone else and saying, "yeah that Jim is a fuckface." then people standing near me should already understand the meaning behind that. There would be no need to ask me not to use that word since the meaning is directed at Jim and not them. I cannot put any blame on myself to how words I use are being interpreted by others. What am I supposed to do? "Ma'am, I'm about to call my friend Jim a fuckface, is it ok if I call him that?"
