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

The McCarthy Era was one of the darkest chapters in American History.  The U.S. government was so determined to root out Communist threats in their country.  Their suspicion was stronger than their better judgment and as a result, many innocent were unjustly accused of either being communist spies or sympathizers.  Some lost their careers while others were sentenced unjustly.  It is a grim reminder that we should let paranoia rule our actions.  We must also defend our freedoms against any unlawful arrest without any proof.  Our freedom and understanding is far too important for us to take for granted. That Era nearly took it away from us.  We must never let it happen again.
