A dissenting group is a group of people who disagree with the majority opinion or ruling. The term 'SECT' is a four-letter word that can be used to describe such a group. A SECT is a religious or philosophical group that has broken away from an established church or belief system. Sects often have their own beliefs and practices that differ from the mainstream. They may also be seen as a minority group, as they are often in opposition to the majority.
