This was me, sort of. I was never really "against" them, I just didn't know anyone that I knew was gay and I honestly didn't really understand the concept. And for a long time, I believed that one little passage in the Book said "it all". But as I have aged, and met a plethora of people in the process, I have gained some understanding and realize that one sentence out of a whole book isn't something that hate should ever, ever be based on. Especially when there are other passages that tell us to do the complete opposite.
