People already know they should be libertarian.
They know right from wrong. They know using violence against the nonviolent or those who aren't violating property is wrong. They know violating property is wrong.
Their only problem is they have been tricked into imagining irrational exceptions to these truths. This indoctrination has taken a lifetime to achieve. It takes one honest moment to shed.
They are probably already libertarian in their heart of hearts. The external statist shell is a mask.
By sharing libertarianism with them you are not trying to "trick them into it", you are giving them permission to be honest with themselves. To be what they already know they should be.
They may still try to fight you, but I hope you offer the chance to everyone you know anyway.
