I never considered that being rude and disrespectful as being "cool".

I guess I see it in a couple of different lights, especially when I don't know the person and their background. They may have been brought up by rude and disrespectful parents and that's what they learned. But as adults, they should have the ability to know what's appropriate and what isn't so they can change their behavior.

Then, there is the thought that maybe they are very closed off people, afraid to let anyone close for fear of someone really getting to know them. Being rude and disrespectful will certainly keep people away from them if that is their issue.

And then, there is the thought that these folks have no empathy or compassion for anyone. To me, that's the scariest thing to think of. The other 2 reasons I mentioned can be fixed, teaching empathy and compassion is most difficult.
