The curious case of Armin Navabi

Armin Navabi is very enthusiastic about challenging peoples beliefgs. He calls to have attempted suicide before reaching adulthood, due to a belief he held at the time that he will secure himself a comfortable position 'in heaven' after he 'dies' (because he committed the act as a child he can still get to heaven, and he is likley to 'fail the rules and regulations' as an adult and not get to heaven at all). He was involved in a major belief system. Nowadays he is saying people who dont believe in vaccination are dangerous for society, but i want to know what reasons we have for believing and he claims there is plenty... He goes from saying "if u believe in the prophet and Quran, u r dangerous" to "if you dont believe in XYZ (vaccination), then u r just as well dangerous"..... better make sure u believe and disbelieve the right things or u could be deemed dangerous.... reasons for belief = Armin said its true (because Professor Dawkins did (reductio ad absurdum)).
