People who spread misinformation about medical or scientific issues (i.e., Jenny McCarthy and autism, Rick Perry and climate change) even though they are not qualified to do so.
Mosquitos. They were bold this year by not disappearing until October. WTF.
Rude and ungracious people.
People who cannot back up opinions political or social issues with facts.
People who brag about money and things they buy with that money.
Explanation by the tongue makes most things clear, but love unexplained is clearer. ~ Rumi
