My thoughts.
You rely on a lawyer for sound judgement when he/she advises you on legal matters.
You rely on an accountant for sound judgement when he/she advises you on financial matters.
You rely on a doctor for sound judgement when he/she advises you on medical matters.
You rely on an an pilot for sound judgement when he/she flies you.
The good doctor should stick with his area of expertise and not criticise the actions of a professional in an area he knows nothing about.
