Quite simply, because Satan has control over the left / cabal / elites / DS / etc. and always goes in complete defiance of whatever God's perfect will and plan is for His creation. Procreation = good, and heterosexuality defined as a man and a woman, was designed by God in the Garden. In addition, God says that homosexuality is a sin. Therefore, Satan goes in direct defiance of God and uses his minions in the world to pushes homosexuality, transexualism, pansexualism, etc. on everyone. Destroy the very essence of what is means to be a man or a woman. Take what God intended to be good and turn it into blasphemy. All current issues in this world right now can be broken down to a battle between Good vs Evil.
