eyeuse2badub - "In dubland, one can be df'ed for smoking which is not mentioned in the bible, df'ed for taking a blood transfusion--which is not mentioned in the bible but not df'ed for marrying an unbeliever which is specifically mentioned in the bible as a n- no for christians. Go figure!"
I suspect the WTS has always quietly wrestled with this.
On some level, I think the GB would love to give JWs who marry "worldies" the boot for the sole reason that - by their actions - they're defying the GB's directives.
The fact that JW women significantly outnumber available JW men, however, makes hookups with nonJW guys virtually unavoidable; the number of DFings would increase to a degree that could cause internal problems. As much as the WTS might want to give any rule-breakers the heave-ho, they can't do it too much without undermining the entire edifice's foundation.
So they grit their teeth and just give 'em a slap on the wrist.
For now, anyway; I've said this before, but these days, I think they kind of want to pare the R&F down to a more manageable size.
