I hope that this Supreme Court case is not a staged Alinsky-type setup where so-called pro-traditional marriage attorneys argue friviolous points in favor of state bans on same-sex marriage.
Politically correct interpretations of the 14th Amendment’s Equal Protections Clause aside, interpretations which activist judges have been using to argue that state bans on gay marriage are unconstitutional, please consider the following. The states have never amended the Constitution to expressly protect gay agenda “rights” like gay marriage. So the states are free to make 10th Amendment-protected state laws which discriminate against constitutionally unprotected gay marriage, imo, as long as such laws don’t unreasonably abridge constitutionally enumerated rights.
I hope that's the way the USSC see it. Otherwise, what's to prevent other forms of "marriage" -- polygamy, incestuous marriage, etc.
