Okay, here's my laundry list. I've thought about it off and on, but I think I've managed to sum it up.
Humans. Nope, just don't like them. Excessive displays of sex and public displays of affection that seem more like the couple is screaming, "Look! We're a COUPLE!" Societal norms - bite me. The color pink, cutesy things, and stereotypes. Being asked if I'm gay because I'm not dating or married yet. Hell will freeze over first. The sun; I like that it makes tasty green things grow and it warms the world, but its sphere of optic violence is pure evil. Winter - it's cold. Religious righteousness - get off my front porch before I burn you at the stake or serve you to the lions. And nothing feeds the hungry or cares for sick or dying more than building yet another church or opening another all religious tv channel. Animal abuse or neglect - I'll euthanize you first for being an asshole. Hypodermic needles - just plain evil (see sun). Traffic (I agree with you, Afke) and art blocks (argh! I completely agree with you, Berit!). Inept doctors that can't or won't help you. Having to be semi-diurnal because of this lame society (I still defy them by being rather nocturnal anyway). People who say or do things just to get a "rise" out of you. People who give me grief for liking and drawing long hair. Seafood, it tastes like it smells.
