The contemporary bible is a compilation of books chosen by men for what the catholic church wanted to further it's cause; it doesn't have all the answers.
The WTBT$ is doing the same thing by handpicking scriptures to fit it's view of homosexuality and further it's cause.
While bible thumpers rake the LGBT community over the coals by using a few loose scriptures, they neglect to acknowledge that homosexuality has been around since the dawn of man. They also don't mention that, until the last few centuries or so, homosexuality was a widely accepted part of many cultures. Why do you think that is?
