yes there is a lot of self-esteem in maintaining the rage..... a lot invested.
Keynes said "if the data changes, I will change my mind" ..... science too holds that respect for data. The anti-vaxxers are unable to change their minds because they have been spruiking that they are right! and no discussion to be entered into, the same as their common stance on global warming.
there's a rigidity that comes with belief, or blind faith.
