This is a case of civil rights being in balance.  Yes, gay couples have rights under the law.  They can marry.  But religious freedom is protected by the Constitution.  And unless you are a religious person who knows the teachings comprehensively and understands what conscience is all about, then you are not in a position to understand that asking any religious person to participate in any way to a gay marriage that they believe is wrong, is trampling their rights.  Gay couples can marry under the law, and religious people are not attempting to prevent them from doing so.  They also are not discriminating against them, because they would be happy in a bakery, to sell them muffins and pies.  The government should not be able to force religious bakers to participate in gay weddings in any capacity that is against their conscience.  And it's not just bakers, but photographers and wedding planners, etc.  Courts need to protect all rights.
