I saw a man on a show that had a near death experience. He was shown people engaging in sinful acts, and the sinners life energy around their bodies was dulled. There were other entities around without the life force, or energy, the living had. These were without the breath of life. They were very dark figures.
The other beings - the dead - waited around until the sinners energy was at it's lowest. The dark entities then entered into the sinners bodies and lived there.
So, you do have a point. Maybe exorcising homosexuals would work.
