The thing is I can see the perspective of these people, even if they're going about it the wrong way. They have good intentions for their friends and family member so they try to introduce them to something they think would help their life.
They might have this feeling that they're selfish or holding out on those close to them. Maybe the person makes money from Bitcoin as a trader or any other means and he would like to educate those close to him about it too, but where I draw the line is feeling it's a must for them to buy the idea.

What I suggest is just tell them about Bitcoin, the features, the advantages, the risks etc. Any one that is interested should go make his own research and you should coach him or her any way you can. Make sure they really understand what Bitcoin is all about and what it stands for. You don't have to get angry if someone doesn't want to use Bitcoin, it's their choice.
