The will of the people of California is that gay marriage be banned. The Federal Government has no right to legislate from the bench. Article One Section Eight of the Constitution says nothing regarding social issues thus the Tenth Amendment is invoked thus the Ninth Circuit was in the wrong regarding this decision. They said it (the ban) violates the 14th Amendment. If the left wants to play that game, we on the right can use that to ban ALL abortions.
Given how the XIVth Amendment indirectly defines personhood with its definition of citizen, a XIVth Amendment based decision could lead to all abortions being legal, including those of fetuses that have reached viability.
