I have somewhat of a pet extension to projection theory... Many people who are anti-gay think that it is a choice as they themselves have made that choice. ie. They are repressed bisexual/gay.
Completely unsubstantiated with no evidence but I find it fun to think about as it would explain their complete misunderstanding of it not being a choice. "I made the tough choice and am living with it, why can't they?!"
Not massively into D&B but this is one of my favourites:
