More crazy ppl in one place is a church.
To me they are all the same
The main difference is simply that churches are legal entities accepted by government whereas sects and cults operate outside of government and are usually illegal. That is not to say that some cult and sect beliefs are all bad it is just the way society works.
Churches r a group of people who all believe in one god that they think every 1 should belive in a cult is the gathering of people who do not believe n god.
