They reason that God forbade the Israelites from eating PIGS was due to the unsanitary way pigs were reared back 2,000 years ago, & so was the consumption of things that have shells. God was wise, back then, people are weren't so educated...PIGS have Swine disease, shell things have poisons if not properly cooked & high cholesterol when properly done. So God set the law...but but people's intelligence have not improved since 2,000 years ago...
The Chinese were said to eat anything that has legs..except the table. But not eating pigs, will make these people, any smarter or healthier?
