Honestly my experience about sharing bitcoin stuff to rest of the world is pretty lame. I have told every person in my friend circle, including the techy cyber persons and guess what they actually are against it because of the same reasons you taught, it's volatile nature, insecurity and less acceptance in the community.

I believe all we can do is just keep the information spreading over forum, blogs, promote good stuff on twitter, YouTube blogs etc.

Let's just agree we can't force someone to like bitcoin.
