How do people like McCance get elected to the school board in the first place? I think we can safely assume that this is not the first time he's made his homophobic views known.
"McCance said that he has received an outpouring of criticism over his comments, including "thousands of phone calls, hate mails, people threatening to kill my family and me."
Most likely this^ is the reason he apologised. Not through any remorse or regret for his outrageous views.
