I’ve always found the “well the original meaning of Leviticus wasn’t homophobic”argument to be pointless. There are other homophobic verses in the Bible, and no religion is truly based on the Bible with no interpretation. It was written a few thousand years ago by whack jobs. Deriving your morality from it is bound to lead you to bad stuff. If you could logic people into changing their interpretation it, you could just as well logic them into realizing it’s a stupid thing to follow.
There is, after all, the whole thing where if you take the literal interpretation of the Bible as direct law, it also:
Forbids eating pork
Forbids cutting your hair
Forbids eating shellfish
Forbids speaking in church, if you are female
Requires you to marry your brother's widow
Forbids wearing mixed fabrics
Forbids planting different crops simultaneously
Forbids charging interest on loans
Forbids making ANY profit above cost on selling food
Makes sex out of wedlock punishable by death
Picking and choosing FTW I guess
But then we're all just talking in an echo chamber here. Much like the man with Leviticus in his truck window, our messages are only to those who already agree with us.
