The Pope recognizes that when the Church demonizes gay folks it loses not only the gay people themselves but their friends and relatives and young people around the world.
The Pope has wisely decided it is better to demonize something invisible so each person can make up the villian in his own mind. He talks often about literal sin and Satan.
The Pope’s actual enemy is not Satan, but the social sciences. It is in the social sciences where myths of the world are exposed. Myths need to be exposed because they drive humans into wars and take people’s money.
The current Pope has recongnized apparently that social sciences have made progress addressing in a rational way certain behaviors in humans. The propensity for large numbers of humans to become addicted to alcohol and drugs has become an illness, instead of a sin.
Mental illness is becoming recognized as something to be treated by doctors instead of by a Christian shaman. Sexual orientation is now considered by the majority as something outside the control of the individual. All this makes domonizing any group of people unpopular.
The only demon available, then, is an invisible one. With sin harder to pinpoint, an all purpose and invisible Satan fills the void left when the social sciences took these behaviors out of the religious realm. This Pope has put his laser on Satan.
Focusing wrath of something so far away it cannot be seen is always safer than condemning friends and neighbors.
