My parents, brothers and friends were the easiest since I introduced them to Seals with Clubs. We are all poker players and unable to play for real money in my home country so bitcoin was a natural fit in my household. I have a couple friends who have purchased bitcoin from me for various other reasons, most to speculate on other alternate cryptos. I find casually discussing bitcoin to strangers or peers is not productive and the conversation always ends up with me refuting arguments invented from sheer ignorance.

I remember being against facebook when I first heard about it so I can understand why some people are against bitcoin. It's easier to hope the technology goes away so you don't need to learn how to use it. Come to think of it I am still against FB  .
