Back to the original question...
I have had a long string of Muslim girlfriends.
That is to say, their parents are Muslim and they are "culturally" Muslim.
I agree with a previous poster that modern, American Muslims of my generation will get drunk and have an orgy long before they touch a ham sandwich. I don't know why... but I don't complain either.
The Muslim dietary restrictions are similar to (but fundamentaly different from) the Kosher "thing." The eating of pigs is prohibited, and contact with them is discouraged, but not anything close to a sin. Just a casual "dont touch the stray dog, Timmy..." kind of thing.
The Muslim dietary guideline is called "Hallal" and involves certain animals slaughtered a certain way, along strict religious guidelines. And let me tell you, Hallal meat is goooood. My girlfriend calls the holiday thing that just ended the other day "goat Eid" because at the end of it they slaughter a goat and give it to friends/family. MmMmmMMMMMM.
