Dear Dgp, I do not think in those paths at all. Sorry if I gave that impression.
I just think that there are more sides in this. Paul is telling this is his personal opinion, and he is telling his opinion to save us from trouble. Intentions have been good and they may very well been suitable for the specific time, even with stricktest interpretation. Our human interpretation of rules turned to principle turned to new rule, do not diminish the good intentions that might have been there. That was my point for that part.
Yes, implementing this view today in hardcore mode is problematic specially for women, for reasons stated earlier.
This is really not JW only practise. As far as I have understood a catholic girl cannot be wed to a protestant boy in catholic church. Where I live both parties must have been confirmed as members of to the main protestant church if they want to be wed in their church. Even where arranged marriages occur, for example Hindu parents try to find Hindu spouse to their children, or the same applies for moslims. Do people in overall care what your spouse's religion is, in general not that enthusiastically as JW do. There are few religions where person get addressed for plans to marry a non-same-believer or even dedicated a public speech about it. In some religions you might get stoned or throatcut for that, but that is totally another story.
