How would you behave in a country that forbid or ban the eating of meat?

I believe no human law is above GOD's law, so the ban should not effect you because GOD allows eating of meat Eating good meat and eating moderately is good for us.

But for the sake of love and not desrepecting members of the society, you try to avoid eating in their presence. And you also inform them that meat is not harmful to us esp if eaten the right way. A just society would investigate your claim, and unban meat eating if found to be true.
Afterall, the purpose of law is for the good of society, people and the world. If you insist on holding tightly to laws that serve no good purpose then you are the problem.
There are good and bad laws. Your law has to be good.
