I think that the people find sects appealing because the people who belong to sects do things that ordinary people like me don't know and we only can imagine. Also is very interesting because the sects are a very old "thing". The Christians are an example of a sect, because the origin of them is the Judaism religion and a part of
That religion forms a group that broke with the Judaism religion. That group will be known as the sect.
But is also other sect as know the Ku Klux Klan. That sect is famous, and know is part of the pop culture, you can ask every one if they know that sect and if you ask them or if you ask me who are they, the common answer that they were a group of man that wear white robe and a white hood that also cover their faces, and the other people that don't belong to the sect couldn't recognize. This people killed colour people, because they hated them. I f you ask me what is a sect, immediately appear on my mind the Ku Klux Klan. I said that they belong to the pop culture because they appear on the movies, on novels; they are (with Hitler) what the pop culture call the incarnation of evil. I don't have much knowledge about what a sect means really or the Ku Klux Klan's believes, but I think that this group of people don't have tolerance for the rest of the humanity; they had misinterpreted the bible (Because they love God)
The ignorance is very powerful as we can see on this people; they are an example of what the irrational mind can do.
