I think the concern that YL is voicing is over how voluntary "voluntary" truly is. I remember this debate among local Muslims about 5 years ago or so, when England permitted some matters to be decided by a Shari'a court (if that is the proper term). Some Muslims in both of our nations were up in arms about the idea...stating that they had emigrated west to escape such a thing.
This is where I part company with some. I see that as liberals wringing their hands and trying to get the government's camel's nose under the tent.
What you appear to be saying is that there is social pressure on Muslims to accept the authority of these courts, so it would appear that they accept such arbitration voluntarily, when in fact they do not.
I can imagine such a thing happening. I also cannot imagine a scenario under which it could be determined if a person was being influenced by their peers or not. I would also venture the guess that YL is not deeply concerned about the poor, poor, disadvantaged Muslim youths who are trapped in their own culture.
To me it is parallel to the subject that Blade96 brought up, that of forced arranged marriages. There is noting illegal about an arranged marriage, but I don't think a forced marriage is legal under civil law. My understanding is that each person must enter in to the marriage of their own free will. But what recourse does a young person have if they are being forced in to this arrangement by everyone they know? Especially in a tight eastern community where the people tend to take social matters much more personally and treat offenders to their ideals with much outward revulsion and disgust than we typically experience in western communities.
How does a person from the outside of such a culture tell whether or not an arranged marriage is truly voluntary on the part of both parties? The alternative here would be to not allow cultures to practice their own beliefs and practices in the hopes of stopping a small minority who might be silently oppressed by such things. Destroy the culture to save it. Invade the right of the family to govern the family itself, insert the government, and for what? To protect those who will not or choose not to speak up for themselves.
At a certain point, one must say that if a person is 'oppressed' and does not wish to do as their family wishes them to do, they must speak up. If they do not, that is sadly their problem. The only alternative is to destroy all family life in order to protect a tiny minority.
No one asked me if I wanted to be circumcised. Shall the government tell parents they cannot perform this religious (for some Jews) ceremony? No one asked me if I wanted to be baptized, confirmed, etc in the Catholic Church. My family doesn't engage in arranged marriages, but my family certainly let me know that they didn't approve of my first marriage and brought pressure on me. Shall the government protect me from them?
When a bride and groom get married and the bride is clearly pregnant, does any government agency step in to ensure that it's not a 'shotgun wedding' in the literal or figurative sense? I don't think so. If both say
"I do" at the wedding, that's pretty much it.
In my opinion, the government's job is to ensure that if a person objects to (arranged marriage, etc), that their right to refuse be protected. If they do not object, I don't see it as the government's job to stick it's nose in. I realize that some weak individuals will thereby be victimized. I'm sorry about that, but I see no acceptable solution for it.
