This is actually a question I can see both sides of, even though I know which side I come down on. And recently a fan wrote in to express the following:
I'm ok with cherry picking religious beliefs in general because I think that it has helped push beliefs towards a more beneficial outcome. Today you hear people claiming that the Christian God is Love and other such nonsense, but I'd rather them intentionally ignore the bad parts in their holy book than to accept it all unquestioningly if they're going to believe in both cases already.
He raised some good points about how it's good many Muslims are moderate--and not like their more fanatical counterparts. I get the point, I really do. But here are my thoughts:
This is a question with no answer. Someone recently posted on Facebook an article about an American association of physicians who initially came out with a position that it's OK to "nick" infant female genitalia as a substitute for a full female circumcision--which they feared some families would go back to the old country to get if doctors here wouldn't do it. However, they then reversed their stance to say that, in fact, doctors should counsel and support the families, but not perform any such ritualistic procedures.
What should they do? Should they cause small harm, in order to mitigate greater harm? Or should they stand firm against all harm?
I compared it in a recent dialog to chemo therapy. Some chemo treatments have long-term, or even permanent awful effects on people's bodies. But the idea is that this toxic cocktail will save someone's life, so we induce harm, in order to mitigate worse harm. And most people agree this is the right course. BUT, what if we found a cure for cancer that inflicted no harm tomorrow, but some oncologists insisted upon continuing to use chemo treatments? Would it still be the right course of action?
Making religion somewhat less toxic, I can see, is preferable to having it be fully toxic. But I personally, as a reformed Christian myself, know that there is a cure available that eliminates the harm altogether. And with that knowledge, I can't, in good conscience, pursue the course of mitigating harm, when a cure that eliminates the harm is available.
I can't speak for everyone--but this is how I view it and how I address the problem.
And I think it also covers the "cherry picking" question. To support a book that encourages subjugation of women and killing other people who don't believe what you do, to me, is inexcusable. It would be like joining the KKK because you like the social networking, but reject the racist agendas.
So, for what it's worth?
