This case is about the same issue that the cases were about in the 1950s and 1960s during the Civil Rights movement, which is to uphold the US Constitution in not allowing discrimination in areas of interest to the state. Commerce is one of those areas. Your need to resurrect this OP when it was sleeping peacefully suggests that you need therapy.
Whether you are a right wing X-tian fundie, Libertarian, Muslim, Gay or Black, discriminating in the marketplace because of your religious, social or political views has been determined illegal by SCOTUS and the various regional courts, in their interpretation of the US Constitution, for decades. It just happens to be gay people's time to gain fairness and equity.
THAT is what this OP is about and THAT is what this social movement is about.
