I think if you asked my Muslim dh if I was submissive, his reaction might be something like this: : However, I do try to respect him, and I do think (from lurking on the biblical marriage threads), that many people say "submit," when they mean "respect."
But the OP's observation on the similarities between the Abrahamic religions is well-taken. I often think part of my problem in choosing a religion is because they are so similar! I love them all!
I think this is especially true theologically speaking if you have a liberal view of Christianity (such as Marcus Borg).
The modesty issue is the first one I noticed. It really piqued my curiosity about other things we may have in common.
Keep in mind I live in the middle of redneck america. I have never had the opportunity to talk to someone IRL that isn't Christian. OK- I probably have without knowing, but never been able to have a conversation.
