@maxdancona,
You need to tell Thomas that sex without coercion is common--he doesn't seem to know that.
You have been alleging (without evidence) that arranged marriages are coerced sex, and therefore rape, and that a "strong man" (i don't remember the exact term you used, and don't care) having sex with women in his group is coerced sex, and therefore rape. Small wonder i think you're channeling Susan Brownmiller. How doe you know that such situations automatically entail coercion? More to the point, what evidence do you have that this was always true, or often true, or even just sometimes true?
Once again, i'm not arguing that the thesis of the authors is incorrect. I'm arguing that they haven't made their case, and you're not helping it. Which is why i continually revert to that special verdict Scottish juries can return, "not proven."
