CMD:  The details of this case are readily available.  The Court's findings are readily available.  The Bakery was found to have discriminated in violation of Statutes regarding protected class status and refusal of accomodations/services.  The case will likely go clear to the Supreme Court regarding the Bakers' contention that their First Amendment Rights include the right to refuse service to a gay couple, based on their religious beliefs trumping the anti-discrimination law.  

I have absolutely no knowledge of what kind of Christian your Grandmother was.  However, I do criticize Christians who use their religion as a tool to justify discriminating against LGBT individuals.  I feel we should allow others to live their own lives w/o our interference so long as they aren't hurting anyone else.  IMO, individuals in consensual gay relationships are hurting no one.  Indeed, I will continue to criticize discrimination against such couples.  I make no apologies for that.  Gary Crum
