Here is something i have been thinking about.
Most problems with religion (JW, Shahira) seem to come from self-established courts. The problem with those courts is that they are allowed to invent rules themselves, and are able to punish people for things that are not illegal, for example sex outside of marriage. There seem to be two factors:
1) People can be punished for things which are not illeagal
2) The punishment goes beoynd membership in a local club, church or company, and affects the punished party very negatively.
Now here is my question: Why does this have to be legal? Especially if the club is religious, what rights would it affect that people are not able to sit down and establish a legal system outside the real legal system?
To me, it would seem that the state has some interest in preventing random courts from popping up, judging from arbitrary rules, but i have abselutely no experience in these matters, and i would like to hear your thoughts.
