Heretics are true believers
Organizations usually encourage mild heresies. This gives them an air of openness and tolerance. But heretics must be burned or beheaded. In a civilized society where capital punishment is abolished, the lives of heretics must be ruined, their careers must be destroyed, they must be ostracized.
Heretics are those who are willing to sacrifice their lives for their beliefs. They are the true believers. Jesus said, Blessed are the meek. They will inherit the earth. How it is possible the grandeur of Vatican can represent Jesus? How is it possible that science, which is supposed to be hungry for truth, is instead hungry for funding? True believers are inevitably heretics.
