They will learn over time trust me.The soft sell is what is best,the more you try to "push" your views the harder they'll push back.Plant a few seeds sooner or later some will grow.

"why do you carry a flashlight,s.a.k ,first aid kit etc"?"the same reason you carry a spare tire in your trunk","I got room for it and someday i may need it."Something along that line.
