I’m having a feeling of déjà vu. Four years ago, I was waiting to see if Barack Obama would be elected president; waiting to see the outcome of a ballot measure in California that would decide the legality of marriage equality in that state; and baffled that a patron of a Colorado library had asked for the removal or reshelving of the children’s picture book Uncle Bobby's Wedding, claiming it was “inappropriate for children” because it showed two anthropomorphic male guinea pigs getting married.
