Don't hurt people and don't take their stuff. If you do, make it right. If you refuse, don't be surprised when people want nothing to do with you.
There are more details, of course. There is the gruesome reality of statism. There are the problems with collectivist thinking and the reality that goods and services aren't free. There are inalienable rights and the non-aggression principle and the inherent illegitimacy of authority.
I don't claim to have the answers to every question or the solution to every problem, but I'm at least willing to take a stand for what I believe in and explain why I hate the state (and became an abolitionist).
