I don’t mean this the way that its sounds, but Scalia’s point that science has not determined that gay parents have adverse effect on children is beside the point imo. The wide, PC interpretation of 14A’s Equal Protections Clause by liberal media, including Obama guard dog Fx News, in support of gay marriage is wrong. This is evidenced by Section 2 of 14A which discriminates on basis of sex, age and citizenship.
So 14A allows states to make laws that discriminate on bases not protected by enumerated rights, sex not protected where 10th Amendment protected power to regulate marriage is concerned, as long as the states discriminate equally against non-traditional marriage.
I agree that the effect on children is beside the point as far as the federal courts are concerned. There is no state which, either by law or by constitution, bars a person from marriage based on that person's sexual preference. There is also no state that does not impose some restrictions on who a person can marry. Along with prohibiting marriage to underage individuals, marriage between close relatives, and marriage to multiple partners, some states prohibit marriage to someone of the same sex. The court should simply rule that this is a state issue.
