First of all, welcome to OCDO. You'll find us a friendly, but honest bunch of folks. We take our rights seriously, even though some on this forum do not and often antagonize us.
I would not pressure your parents to learn. Read these forums and other related articles and books. Read enough and you will begin breathing and living those things and it will eventually rub off. Sometimes it won't, but I found in several of my scenarios, this was the case.
Good luck and happy carrying!
