I don't keep kosher, but I don't eat pork, and I won't allow pork or shellfish in my house. Most of my family and my Jewish friends do the same.
Actually, most of the laws aren't in the Torah - they have been built up over the centuries as a way of "building a wall around the Torah" and making absolutely certain you don't "accidentally" break a law - but if you've been studying Jewish law, you already know this
This is why, for instance, I don't care about mixing meat and dairy. The original commandment is to not cook a kid in its mother's milk. This has been expanded to forbid mixing any meat with any dairy (and show me a chicken that can produce milk
). Those who keep strictly kosher have separate plates and silverware for meat and dairy, and won't eat dairy for a few hours after eating meat. I think that's overkill - but that's just my opinion, and I have a lot of respect for those who do make the difficult decision to keep strictly kosher.
Hope this helps
