What would you do when you're talking to someone but then he suddenly talks about his hatred on Bitcoin, what would you react to it?
I've never actually experienced anything like this before, I just want to be prepared when it happened to me.
Nothing. Just let them be. They don't know what they are missing out then. You can't blame them for not liking bitcoin. Maybe they have their reasons and let us just let them be. If ever I would meet one, I wouldn't mind explaining anymore or persuading them. Bitcoin is one of the things you don't want to miss on your life and not liking it won't do you any good.
