The comparison between Homosexual Marriage and Inter-Racial marriage is not only ludicrous, but moronic at best.
NO one can choose the color of the skin they will be born with or their gender or their ancestral heritage and ethnicity.
EVERY Human can choose whom and what they will have sex with.
The ability to reason and and make choices based in facts and logic is what separates men from animals.
Those who contend that they have NO ability to choose whom or what they will have sex with, are in the same breath contending they are less than Human or sub-human.
