Good question. I would think that the board members and Thomas More would be liable. Especially as the board acted against counsel recommendation to implement More's suggestion.
How the "liberals" work. This is ACLU vengeance. Not only must they win, they must make the losers hurt so badly that fewer people, each time, will dare to even raise their voice, let alone do something that the Anti-Christ Lawyers Union disapproves. A politician could make headway in a campaign by bashing the Anti-Christian Liberal UnAmericans and their methods. It is one sign of poor Republican leadership that this is rarely done, except in fundraising letters to us.
