What is the best way of dealing with people who are disrespectful towards you?

There are several things you can do when someone has no repect for you. You can completely ignore their rude comments and behavior and "kill them with kindness," thus, contusing them. Depending on your relationship with the person, you can totally ignore them, not only their rudeness. Or, you could use my mother's favorite line, "You can't insult me -- I have no respect for your opinion."
