I'm in a dry enough mood to actually post my opinions here.
People who drive down the road playing loud music with the windows wound down. You're not impressing anyone.
People who smoke anywhere that forces non-smokers to breathe their smoke (including while walking down the street).
Not homosexuals themselves, but Christians who say the Bible doesn't say homosexuality is a sin, or say that the Bible does say the above, but God has changed his mind about it purely because we want it to be ok.
In fact, basically any part of the Church that ignores Biblical teaching. It's like those guys who buy flatpacked furniture, throw away the instructions straight away and wonder why none of it held together.
Carrying on from that, anyone who blames another person, company or institution for any bad thing they did themselves.
People who condemn the government for messing up when to be frankly honest, what could they possibly do better? If a politician deliberately or knowingly messes up then fine, but it's not right to blame a politician (or any other person) for something beyond their control.
Russel T Davis, for being a rubbish writer.
People who say Creationism is bad because it takes away 'glory' from the theory of Sheer Dumb Luck.
And, you know, the Irish, French, Americans, Indians, Muslims, Atheists, old people, teenagers, punks, chavs, goths, emos, English people who mispronounce schedule as 'skedule' when it's pronounced 'shedule' or lieutenant as 'loo-tenant' when it's pronounced 'left-tenant', anyone who makes or listens to R'n'B and similar, and actually pretends that it counts as music, ganstas, rappas, people who drop litter, pre-pubescent girls being encouraged to act like mating animals and parents who allow or encourage this, and anyone who's bowels have been hurting for the past five years yes I'm looking at you.
