@philcolbourn @ned theyre usually not ready. The heterodox free rational thinkers are mostly already on the anti-pharma side, leaving those who dont want to do too much thinking they will just follow their feelings and its easier to do what the tv says than think.
I like to ask them first 'what evidence would change your mind' if they dont have a good faith answer (you should have an answer yourself), their mind is closed and they are not ready, treat them with love and give them more time.
