Prop 8, or the California Marriage Protection Act, is being challenged in federal court in January and could have nation-wide consequences.
My personal view? Legalize marriages between people of the same gender. If a church or religious organization is not comfortable with that, don't make them perform the ceremony, but allow other churches and civil authorities to proceed. This may open those objecting organizations to discrimination suits, but I believe it is their right to object, just as it is gay peoples' right to get married.
Simple enough, right? Why can't we all just get along!
