Rudeness in and of itself isn’t an issue imho. I’d rather someone get to the point with me and be rude than other things that annoy me. I think a lot of people misunderstand why some are rude. I think a lot of people take my abruptness for rudeness. It’s not, I just value my time. Please don’t waste it. If I’m giving you my time, it’s because I value you.
(My opinion)
Other things that are worse than rudeness:
Willful ignorance, after being corrected on a subject, continue to be wrong.
General rage/anger, calm down before you die of a heart attack. It also makes you forgetful.
Cussing. There’s simply no excuse for it. It’s crass and makes you dumber. Instead of using our vocabulary, cussing tends to replace a whole host of words.
Being offended at everything, these people need to simply grow up. I don’t care what I said that offended you. You may find me rude, but I find you insufferable.
Mindlessness. This one bugs me the most I think. How can so many people go through life asleep at the wheel?
If you run into a lot of rude people, go through my list and see if you fit somewhere on it. Be honest with yourself. You might find that the people who are being short with you, simply find some easy to fix flaw annoying. Also it could be that you’re in the wrong line of work and need to find better employment.
