Those who punish others.
Those who gang up on others.
Bruised egos that turn violent.
People who trust media.
People who dismiss refined taste as "hipster".
People who can't imagine others being more intelligent than them.
Being interrupted while I am concentrating on something
Having to wait for long in: chairlift queues, security, customs, restaurants
Rap, pop, hip hop, electronic and metal "music"
Ideologues who refuse to consider any piece of information that contradicts their worldview. It's one thing to be ignorant. It's another thing to consider ignorance wisdom. There is no value in sticking to a conviction if it happens to be moronic, the way I see things. And it's good to be sure that it isn't moronic, too, before you act so damn certain of it.
