I happen to have a Gay son and, though it doesn't matter in this case, am in favor of Gay marriage. But if there was a wedding and someone felt uncomfortable doing the catering I would find another caterer. I can understand why some people may feel uncomfortable and can respect their feelings while the dogmatic Leftists can't. There will be constant clashes between all these groups and there will never be a winner, or peace, if we remove common sense, discretion, and the rights of others from the equation.
The Leftists seem to believe that this is a victory for a freer and more open society, as though only laws can ensure that, when in fact society will become more restrictive and the right to 'live and let live' will be less common.
