As I understand it, being gay is not a sin in the organization, only homosexual acts are sins. I've never read anywhere that gay JW people are encouraged to "fix" their gayness and marry.
I've certainly known a fair number of confirmed bachelor types who live exemplary lives in the Witness sense - one life-long Bethelite I knew springs to mind - but are clearly (to me anyway) gay. They've all been in the closet though.
I wonder if any JW has ever been out of the closet, but not disfellowshipped since they don't have sex? Or even, out of the closet with "privileges" in the organization?
Single heterosexuals can say "I'm heterosexual and celibate since I'm not married". Can single homosexuals say "I'm homosexual and celibate" without any repercussions in the congregation?
