The closest cult we know of is on Rice Lake called the Moonies led by Reverend Myung, where I have currently visited. Cults can be involved in churches and even are earliest religions are called cults. Cults are not the strongest groups' sects are the strongest group. When you join a sect you cannot get out of them but a cult you can leave without having any problem or commitment. Sects will not let you out because many times it's illegal and they are afraid that you will say something to the public.
Cults sometimes are illegal to.
Famous athletes are a big figure when it comes to cults, many times Movie stars, professional athletes will endorse a product and a trend will start, making it turn into a cult. Also people who generate beliefs of something like flying saucer, aliens or any unknown figures can be cult. In religion when people call a church they are referring to a sacred organization having a highly structured or formalized dogma and hierarchy, but also allowing a bit of flexibility about membership requirements allowing you to go to a church and leave church when you want to. Although sects are against church attempts to accommodate to secular society. Sects believe that they are protecting a true faith or belief.
