In the bold - I am quite curious; If that person is making his/her points, In your eyes, Why would it still make that person look less intelligent when using profanities? What if that person wants to use the profanities to be able to express their feelings/emotions? What if that person has no idea or knowledge of how to bring it's point other than using the profanities?
I'd agree with you on that, although, Can you elaborate on how it is viewed as a person who is socially awkward by using profanities? Is it because this person could not virtually hold or carry a conversation other than using the profanities?
