What lessons can be learned from the mccarthy era about what u. s. citizens need to protect in order to preserve the democratic political system and american way of life

We must never give in to exaggerated fears and must continue to fight for our rights to express ourselves and not have our movements be monitored by government.  We must also protect our rights to fair trial that the McCarthy Era tried to destroy.  No one should be subjected to witch hunt or be branded a traitor or spy without the benefit of a fair trial.  The McCarthy Era played on people’s fears but it also destroyed people’s lives. We must never let that happen again.
