I just don't believe he has the right to say "vegetarians must give up their vegetarianism to get well". He can tell people that in his opinion eating meat aids the healing process, but it's just as unethical to say to someone that they "must" eat animals when it is against their conscience as it would be to tell a pregnant woman that she "must" have an abortion to survive. By all means give people advice, but to tell people they "must" act against their conscience is wrong.
