The need to use profanity is a clear sign of a poor vocabulary and an inability to articulately express ones self. It can also often be a need to sound rough and tough. Some of the toughest men I have ever known never swore no matter what happened. That sure didn't make them shrinking violets that needed anyone to protect them, nor were they guys I was afraid to have covering my back. Just the opposite in fact. I see no upside to allowing or tolerating profanity on a public forum that I quite happily let young children read and enjoy. Not ALL customers are of the same value, in business I have told a fair number of customers to go elsewhere. Their personality, business practices or in some cases lack of honesty didn't align with my way of doing business. I never really missed the business and tremendously enjoyed the people I did deal with.
