Do you think the immature rhetoric of insults help

Do you think the immature rhetoric of insults help you gain credibility? If you are a representative of this company's and the "talk" your suggesting then I will pass on your offer and reach out to the company myself this week like I have done in the past (the grown up adult thing). But if you would like to have a face to face discussion then I welcome that as well. My schedule is pretty flexible, and need an excuse to use some sky miles.
