Hate for Hate's Sake
OK, I admit it.

I hate George W. Bush. He's a liar and an elitist who has tricked the majority of Americans into thinking he has their best interests in mind when he's really raiding the fortunes & prestige of this country to line the pockets of the richest 1% of the population while wrapping himself in a false cloak of Christian piety.

I know lots of people on the opposite side of the political spectrum hate Bill Clinton. They think he's a liar and an elitist who had tricked the majority of Americans into thinking he has their best interests in mind he's really giving their hard earned money away to people who don't deserve it while simultaneously receiving adulterous oral sex.

See how, in this article from the New Republic, why we all hate at least one of these guys, although some hate is more legitimate than others.
