Don't misinterpret what I write and there won't be any problems.
I don't want to pad my posts with unnecessary filler just to make it sound nicer, especially when I don't think they sound all that bad to begin with. If I said, "Hey, idiot! Can't you get anything right?" then I can see people getting upset. But my posts, IMO, are polite and well thought out. I always have other posters' feelings in mind and don't want to hurt anyone. I can't say anything for my tone, other than you are obviously reading too much into it.
