Here is the link to the 2007 letter of Flanders, although I understand he may have been seeking revenge and then sunk himself. But I had assumed he really did want to expose what he believed was the hypocrisy of the youth organization:
I read the letter, pretty sick and disgusting. An 18 year old man having sexual relations with a 14 year old. The gay lifestyle, all it brings is torment, unhappiness and stupid drama. This is also proof that sex outside of marriage only brings grief.
