no, you are missing my point.
married gays will march into court, and argue that since their marriage doesn't offer the same opportunity for bearing children, they should receive special treatment to achieve parity. special treatment in the tax codes, special consideration for adoption (that will be the big one) - anything and everything to make their marriages on par with heterosexual ones.
Yes, they will march into court. Nothing can stop people from filing lawsuits on whatever they wish. They had better have a compelling reason, or risk not getting what they want.
