What Do I Do When I See A Narrative Against My Belief ?

If I see any story or narrative against my belief then I would listen it calmly rather than reacting recklessly. I would like to listen the narrative & story and I would appreciate if an argument with proof would be presented as well as it can be helpful to bring a change for betterment as only the person who doesn't have similar belief will only be critical to the belief and it can be helpful and harmful as well so it would be my responsibility to make the constructive criticism helpful in change for betterment and also to ignore the destructive criticism & to give a simple, but an efficient message to the person who is spreading distrust would simply be -

Love Peace And Hate Hatred!
