Isn't re-incarnation part of the Hindu faith? I'd heard that's why Hindus don't eat meat, it could be a loved one in a new life.
As for Muslims, I live in a College town & there is a strong Muslim community here. After about 20 years in the pizza biz,
I've learned that dietary concerns are similar to Kosher. Beef & chicken are acceptable to the Muslim customers I've served.
Perhaps InvincibleDonkey's friend belongs to a specific group, like Seventh Day Adventist Christians (also strong in local
community). Have also heard of some Jews being relaxed on the pork issues, although not common.
Maybe our leaders should play GTA, actually learning a little about other cultures here.
