Freedom is never more than one generation away from extinction.

My Take:

If we do not pass on to our children and their children how precious and ephemeral our freedoms are, they will not just lose them, but gladly give them away.  This goes beyond the RKBA movement.  People who let others tell them how they should worship, how they should speak and write, or that criminals do not have at least some rights are not much more than slaves to their government.
