My not-so diplomatic dad

Sometimes, I am envious of my father.  With the exception of his brief stint in the Air Force, my father has never had to answer to anybody except God and he has been free to speak his mind.  In my father's world, PC means personal computer.  Unfortunately that is not the case for me.  I feel like I am living in some strange Orwellian society where the thought police are dictating what I say and what I think.  How do I teach my children to live in this world? How do I teach them not to be afraid to speak the truth even if the truth hurts?  Perhaps I will read them the children's allegory on the Holocaust which is based on the following quote:

"They came first for the Communists, and I didn't speak up because I wasn't a Communist.



Then they came for the trade unionists, and I didn't speak up because I wasn't a trade unionist.



Then they came for the Jews, and I didn't speak up because I wasn't a Jew.



Then they came for me, and by that time, no one was left to speak up."
