If you sample any active Internet discussion forum, you will find that the majority of the posts are belligerent and disparaging. This does not surprise me one bit because many (if not most) of our interactions with others will not be sweet. Given the lack of consequences towards disagreeable actions on the Internet, I'm almost positive that the incidence of such behavior rises significantly (even amongst people who are generally considered even tempered).
The reason I bring this up is because human behavior on the Internet fascinates me. Anyone else interested?
