You should hate someone because they're an *******, or a pervert, or snob, or they're lazy, or arrogant or an idiot or know-it-all. Those are reasons to dislike somebody. You don't hate a person because someone told you to. You have to learn to despise people on a personal level. Not because they're Red, or because they're Blue, but because you know them, and you see them every single day, and you can't stand them because they're a complete and total ****ing douchebag.
