The left in the United States has constantly drifted further and further from the values that founded the nation. Socialism and Communism are openly endorsed by Leftist presidential candidates. Many on the left openly espouse doctrine that they admit is founded in Marx, Lenin, or Mao. Where any social construct that supports traditional or constitutional based values is persecuted. Surrendering American sovereignty, no personal property, race based social engineering, excessive taxation, destruction of the family, and eradication of faith-based beliefs are becoming commonplace perspectives on the left.
