I disagree. It's an effective way of conveying emotion and in so breathes "life" to the words. It's a gentle reminder that the person typing these things is human; bringing along a range of complicated life experiences and emotions that you may be unaware of. Perhaps you need to look inwards and discover why something that is ordinarily insignificant brings you so much frustration. Is it from a preconceived idea that swearing implies a lack of intelligence? Time for some introspection.
