Rude people.
Condescending people.
People who cannot formulate their side of a debate without resorting to insults or nonsense with zero credibility they tout as "fact."
People who do not respect their elders, military servicemen and -women, or judge others based on external appearances.
So-called "reality" shows designed for people with no intelligence, such as Jerry Springer, Fear Factor, etc.
People who are picking someone else up for work early in the morning, and instead of getting their lazy asses out of the car, they blow their horns over and over again until the passenger emerges.
Racists, and anyone who flys the race flag because they think they are entitled because their 4th detached ancestors were oppressed hundreds of years ago.
Christian bashers.
Christians who preach their ideas at every chance and shove it down others' throats even when it is blatanly obvious the other person is not receptive.
People who get in the middle of the two extremes listed above - and you can substitute "cops" for "Christians" and get the same result - instead of letting the subject die. What is it wih people who enjoy fanning the flames?
Being told I have to accept homosexuality, and homosexuals who demand equality and preferential treatment at the same time. You either want to be treated different, or you want to be equal - you can't have both. Same with feminazis.
Anyone who refuses to help a friend.
Anyone who uses friends that want to help.
Cheating and infedelity.
