One correction for Sorbo: People weren't boycotting Chik-fil-a for "being christian". There are tens of thousands of businesses that are "christian". It was Chik-fil-a's large donations to homophobic groups and the president of the company at the time Dan Cathy (and current Chairman of the Board) making public homophobic statements.
Be whatever religion you want, but when you use your money and power to repress other people, that's where you earn a boycott.
