Fundies always like to compare homosexuality to murder, bestiality, lying or stealing.
Why not try comparing it to something it matches? Left-handedness is virtually a perfect match.
Being left-handed occurs with about the same frequency as homosexuality. There is also a range for the preference, from pure left handed to ambidextrous to pure right handed. Attempts to get the person to change *might* be possible, but doing so invariably damages the person seriously. People have hated lefties because they are "different". There is nothing to being left handed that harms anyone, but people have been ashamed of being left handed, and have been tormented by others for being left handed. There are cultures where being left handed receives condemnation at least equal to the condemnation given to homosexuality. Just try waving to someone in one of those cultures with your left hand, or even (horrors!) *eat* with the left hand. There is even a word meaning devious and evil that comes from the term for being left handed -- sinister. Being left-handed is the "sinister" sin.
People have used the Bible to justify hatred of lefties, including condemning them as witches just because they were left handed. These are actually a lot more convincing than the ones used to try and support a misdirected effort to condemn homosexuals.
"And now if ye will deal kindly and truly with my master, tell me: and if not, tell me; that I may turn to the right hand, or to the left."
The connection would be that "dealing kindly and truly" would be related to "turning to the right hand", and NOT dealing truly and kindly would be associated with turning to the left (hand). On the other hand, think how the fundies would use the passage if the last reference was to marrying a woman or marrying a man. Assume it had THIS wording: "And now if ye will deal kindly and truly with my master, tell me: and if not, tell me; that I may marry a woman, or must marry a man." I could not imagine this being overlooked as a gay-bashing passage.
Genesis 48:14 "And Israel stretched out his right hand, and laid it upon Ephraim's head, who was the younger, and his left hand upon Manasseh's head, guiding his hands wittingly; for Manasseh was the firstborn. 17And when Joseph saw that his father laid his right hand upon the head of Ephraim, it displeased him: and he held up his father's hand, to remove it from Ephraim's head unto Manasseh's head. 18And Joseph said unto his father, Not so,my father: for this is the firstborn; put thy right hand upon his head."
Here the left hand is clearly shown as being lesser than the right hand. If the only mentioned difference between the two was that one was gay and the other straight, with the implication that the lesser blessing should go to the gay, I cannot imagine it not being used as a gay-bashing passage to show that gays are "inferior" to heterosexuals, and that they do not "deserve" approval or blessing. Or, assume for the moment, that the father was giving each in marriage -- one to a woman, and one to another man. It would show the sons fighting to NOT be married to a man, and therefore would be a major gay-bashing passage.
Ecclesiastes 10:2 "A wise man's heart is at his right hand; but a fool's heart at his left."
Again we have a clear condemnation of what is at the left hand. You can see here how people could use this to abuse lefties, claiming they are "fools". Imagine for the moment that the passage had said" "A wise man's heart is to love a woman, but a foolish man's heart is to love a man." Can you imagine that NOT being used as a major gay-bashing verse?
So why not start a crusade to get rid of lefties and "save" them from their "sin"? Why not make it illegal for lefties to marry?
