It has nothing to do with Jews or not Jews. God sanctioned slavery because nobody had money at the time, and it was the only way to repay debt to another person or family.
First, people had money at the time. For instance, one of the verses in the bible says you can sell your daughter into slavery, while another says you can get away with rape by paying the father of the victim 30 shekels.
Second, the Bible's laws on slavery makes distinctions between non-Jews forced into slavery and Jews sold into slavery because they couldn't pay their debts.
But that's the point. They are a church that read the bible and said, "Yup, says right here, Shellfish is an abomination, just like the gay sex." Some churches are okay with shellfish. Some churches are okay with gay sex.They are one fucken church you moron. They are not accepted by the general Christian religions.
So who ever forced you to buy kosher products?
No law supersedes the US Constitution because the US Constitution is the law of the land. Laws have been overturned because they were unconstitutional. Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof. When you tell a business owner he must violate his religious beliefs to accommodate a customer, you violated his free exercise of religion.
Again, slippery slope, buddy. If you tell the local states that a regulation on business can be ignored because your imaginary friend in the sky says so, it would be impossible to regulate business.
Sanitation standards? Sorry, man, nothing in the Bible about those, you are violating my religious beliefs!
