Will banning of meat products ever bring change in people's eating habits if no, why are politicians after such a truce..?

Meat products will never be banned, farming would be destroyed.

the proteins in red meat are widely agreed to have been responsible for our brain growth.

If a totalitarian state decided to ban meat, people would just find it elsewhere and create a black market. Remember recently how people literally smuggled into their country using underground tunnels KFC products?

Banning food that we've been eating for over 2 million years simply because some people think it's unethical. How typical.

It might help if people knew what the heck you are talking about. No one is banning meat products around here except in the event of health risk.

Like other cultural habits - many libs think you can change culture by a law!!! Idio*ts!
