The WTS will never accept homosexuality, OTWO. Its leadership would rather die and rot in Gehenna's basement first. That would be akin to letting "apostates" remain in the ranks of Jehovah's Witnesses for as far as the Governing Body is concerned, LGBT people might as well be apostates. When I was confronted with 1 Corinthians 6:9, 10 by my judicial committee, I turned the tables on them by asking that since Paul also mentions drunkards in that passage, did the WTS understand him to mean that such people could now consume alcohol since they were 'washed clean' and therefore had no reason to fear a relapse. That question was met with an angry and frustrated silence as they realized that could not be the case but that conceding the point was rejecting WTS doctrine and therefore apostacy. Thereafter the committee focused its questions on how loyal I was to the Governing Body and not on whether I was a gay man or not.
The WTS still believes that being gay is a deliberate choice and that fervent prayer, regular meeting attendance, intense personal study and active canvassing are enough to purge it out of a person's mind and heart. If the leadership were to espouse any other viewpoint, this would open the floodgates to accepting other things which run directly counter to WTS theology. And once that acceptance became a reality, the chokehold the leadership has over the rank-and-file would be broken and the organization would implode. We need to constantly remember that this is a cult and the only way it will make radical changes such as accepting homosexuality would lead to its destruction.
