Interesting, I did not know any of that.
We have someone who is Jewish and tries to remain kosher, although it’s difficult when she visits us. Even though she does not ask us to do so, we try to keep as “kosher” as possible. But some of the rules are difficult. Fish is strange, for instance. Fish with skin is not kosher, but fish with scales is OK.
The hardest thing, though, is the dairy/meat prohibition. This is also one possible reason there is higher heart disease in Israel, as the obvious thing to do is use seed oils.
Personally, I don’t see why both science and religion can’t coexist.
I also have listened (since I have a 30+ minute drive each way to/from work) to many texts, including an interesting one comparing Jesus and Mohammad. There were many parallels (not much is known of either’s upbringing, for instance), but differences too.
