Pondering and probing into another's sexuality, whether to his face or behind his back, is not only uncivil but sinful and proud, as Christ called us to self-examination, not to put others under the moral microscope. Seeking to "out" another or to suppose and force discussion of a lifestyle that he does not openly relate to others is not only sinful but harmful, and definitely not a call for a Christian.
Sexual orientation is only a very small portion of each very complex soul that God values. It's time that Christians adopt this view.
Each person has his own closet. So I find it quite strange that we "Christians" force some closet doors open to be rummaged through and aired out while others sit without upset, dusty and settled—like gossip, exclusivity, and haughtiness. I guess it depends on how interesting the closet's contents are—and which bad habits work in favor of keeping the rumor mill moving and fingers pointing, keeping our "religion" interesting so the journey doesn't seem so very monotonous, tedious, so puritanically bland.
So the next time I witness another attempting (however coyly) to pry open a door in order to "out" the contents of someone else's closet, I fully intend to ask if she would like to open her own and allow others to take a tour, deducing what they may of her life and taking away only those things they wish to expose.
