Most talented hackers are gentle, friendly creatures with a versatile sense of humor. Hackers universally abhor senseless violence, in fact senselessness or violence of any kind. The most pacifist of all varieties of humans, their peace trappings may often make them identify with, and be mistaken for 60s hippies, though there is a lot that sets them apart from people whose experience with virtual reality is limited to the use of psycho-active drugs. Some hackers have experimented with a variety of drugs nevertheless, and all would agree that nothing really beats the high you get from hacking a complex system. Creativity and intelligence are the ultimate trip.
Hackers automatically resist and rebel against external authority of any kind.
They also love to de-emphasize its importance through humor and practical jokes designed to embarrass rather than wound, because they know that the only way to deal with someone seeking authority is simply not to grant them any . Authorities don't exist in nature, they are created by human beings. We can collapse their authority by collapsing the aura of authority. A bumbling clown has no authority, only amusement value. It is very enlightening to observe an encounter between a puffed-up authority and a skinny, fidgety, bored hacker looking for something to entertain himself with.
