Frankly, my impression of most moderates is that they just ignore the passages that make them uncomfortable. That's the same thing the Fundies do, it's just that they've happened to come to the right conclusion based on the same ass-backwards approach. Of course you have your occasional theology scholar, or well-read Scotsman, but they are not whom I'm talking about.
If you have a brain and are even a little religious, you have to realize a few things:
1. The Bible (or whatever your holy text of choice may be) was written by humans, gone through numerous translations and re-translations, been redacted, added to, edited, lost, found, subjected to public inquiry, lost again, and finally buried in soft peat for three months and recycled as firelighters. It is ABSOLUTELY necessary to approach a holy text and be able to see, or at least make the attempt to see, where the cultural, political, and historical biases of the authors/translators have crept in. You have to make the effort to tell which parts are cultural (no shellfish, women shut the hell up in church, no mixed-fiber clothing, circumcision, anti-gay prejudices, etc.) and which parts are doctrinal (Jesus is the Son of God, the Golden Rule, John 3:16, etc.).
We have a problem in the USA in that a large portion of our Christian religious heritage is either exceptionally conservative and reactionary (evangelicals and protestants) or astoundingly legalistic and moribund (Catholic and Orthodox). Both of those flavors of Christianity unfortunately share a few of the same cultural values that the bronze-age nomads who produced the Bible did, such as the devaluation of women, exaltation of patriarchs, homophobia (but really only male-male homophobia), a rather unfortunate penchant for ethnocentrism, and a paralyzing fear of change. So while the mainstream Christian traditions in the US (and largely Europe as well) reject many of the cultural bits that are in the Bible (like the no shellfish thing, the head-covering of women thing, the no-shaving for men, and the like) that are not shared while whole-heartedly embracing those bits with that are unfortunately still shared (like the homophobia thing).
Because these cultural biases are shared, the mainstream Christian traditions have moved them from the "cultural" column to the "doctrinal" column, and once moved, to put them back where they belong would be to admit error, and there we run into the whole "fear of change" and cowardly reliance on tradition to establish truth.
