Niche religions are small religious groups that are often considered to be outside of mainstream religion. These religions can include SECTS and CULTS, which are both terms used to describe a group of people who share the same beliefs and practices. SECTS are typically smaller than CULTS and have a more structured organization. CULTS, on the other hand, are usually more loosely organized and often have a charismatic leader. Both SECTS and CULTS are often seen as controversial due to their unorthodox beliefs and practices.
