I know.
"Sharia" courts in England operate the same way.
Private arbitration be it whatever religion or no religion, as 99% of all private arbitration is, is ok with me.
None of that is the law and binding on anyone else in America other than the parties that agreed to it to begin with.
But as the investigation in England found out....many of the "believers" are basically forced to submit to the Sharia courts.....and there are many human rights violations....
No different from Beth Din courts here....
