I agree.  For me, the issue is not only that civil communication sometimes becomes impossible.  It goes to exactly your point: rape is a profoundly sensitive issue, as are many of the other things we discuss here.  There sometimes comes a point when the back-and-forth is not conversation, dialogue, or even disagreement, but just a pretext for continuing to post horrible things in defense of indefensible claims and ideas.  That's why I decided, probably later than I should have, to cease and desist with 'seektruth'.
