Communism is not a political party nor a political plan under the Constitution; it is a system of government that is the opposite of our Constitutional government, and it would be necessary to destroy our government before Communism could be set up in the United States....[Communism] even reaches its hand into the sanctity of the family circle itself, disrupting the normal relationship of parent and child, all in a manner unknown and unsanctioned under the Constitutional guarantees under which we in America live.
