Rudeness
Rudeness was a behavioral expression of disrespect or a lack of courtesy that would breach social norms. However, rudeness could cause negative emotions in others, such as anger, hostility, and disgust.
In 2259, Captain Christopher Pike realized that the R'ongovian diplomats were rude to the Tellarites, reasonable with Humans, and deeply logical when talking to a Vulcan. (SNW: "Spock Amok")
