Things exploded at book club last night

Maybe this is repetitive but it just happened last night so it's fresh on my mind.  I've been attending a book club with my right wing christian neighbor ladies for four years.  We have had a few political discussions although we try to steer away from it in general as they are aware that I am a loyal democrat who despises Bush and thinks the war in Iraq is morally wrong.  But last night all my anger, angst, and disgust came spilling out.  

We had read the book The Gilded Chamber, a novel of Queen Esther, by Rebecca Kohn, a "sumptuously evocative novel of the biblical heroine who sacrificed love to save her people from extinction and became queen of a mighty empire".

No way to discuss this book without mentioning the bible.  We all should have known better.  What I didn't anticipate, although I had prepared myself for a biblical discussion, was the comments made about Jews and any other religious person who doesn't happen to be a born again christian.  In a nutshell, that none of them will be granted admission into the kingdom of heaven.  

While I have always enjoyed political discussion,  I recently have avoided bringing up politics with someone I know is a bushie.  It just gets too nasty.  I have now shifted my approach; if it is brought up I will not sit by and allow someone to spew out untruths.

So, it was them against me, things getting pretty heated, and I told them they were hypocrites.  Where is the outrage I asked over the death of 30,000 civilian Iraqis?  But in the end I got to ask my all time favorite question of the pro-life republican who stated that abortion was her major issue.  "If it is such a major issue to you, why have you not adopted a child?  There are children who need homes and there will be even more of them if abortion becomes illegal?" Answer;  Deer in the headlights look, stammer, "I have two kids already and don't think I could be a good mother to three".

So, should I stay or should I go?  What is the best way to handle what is becoming a national dilemma, neighbor pitted against neighbor by the powers that be who profess to be "moral and upright christians"?
