There's no need for us to force them to like bitcoin. With the price increase of bitcoin, it is enough to make those people believe and start to like bitcoin. But yes, respect is needed and give them the decision if they will voluntarily tell us that they like bitcoin. Just let them see you are enjoying with bitcoin.
Yes don't force anyone if they don't like bitcoin. of course in beginning people will not believe this very quickly. Just tell them what is the price of bitcoin today, this is the first step to making attract people to this bitcoin. Next, if they show interest how to make bitcoin give them a small introduction. If they do not believe let them go don't force that kind of people it is time waste for you.
Base on my experience, when I started to tell the price of bitcoin to my friends. It started to give them some attention but still I don't insist with their interest. Most of them are just attention seekers and they know the price of bitcoin is totally high but they don't want to work hard. As if that they want some instant bitcoin.
