The people decide the laws and the punishments for them. If they decide to execute homosexual pedophiles while giving lesser sentences to heterosexual pedophiles that is their legislative perogative unless it violates the BoR...which is absolutely silent concerning faggotuality.
The Fourteenth Amendment provides equal protection under the law to all citizens.
Which in no logical manner can be construed to refer to homosexuality. Homosexuality is a BEHAVIOR and behavior is exactly what the law seeks to modify and punish. Homosexuals have full constitutional rights in that they have the right to assemble politically, petititon for the redress of grievances, freedom of the press, freedom of religion, the right to be protected from unreasonable search and seizure, the right to keep and bear arms, the right to vote etc etc etc
That is what the 14th Amendment protects.
The corollary is: if homosexulaity is a 14th amendment right then necrophilia, pedophilia, incest, etc also must be granted equal protection under the law; but this claim is absurd on its face. Faggotry is a political fad, not a fact of law or morality.
