McCarthyism is the practice of making accusations of disloyalty, subversion, or treason without proper regard for evidence. It also means "the practice of making unfair allegations or using unfair investigative techniques, especially in order to restrict dissent or political criticism." - from Wikipedia.
The Leftist in our country, especially in the entertainment industry, have long condemned Senator McCarthy's attempt in the '50s to purge socialist-communists from our very influential entertainment industry. Even to this day the lefts definition of McCarthyism per Wikipedia's definition is considered a bad word in America.
It was not until the fall of the Soviet Union which exposed documents that McCarthy was right about the communist threat and also proved that many he purged were in fact Soviet Communist operatives.
This poster taken from the '50s warns of the threat we all now are experiencing. In the poster it warns of "One-Worldism" what is commonly called today Globalism or a One World Order.
You see One-Worldism is Communism/Marxism/Socialism/Globalism.
A One World Order has always been a communist's promise. Workers unite around the world for the greater good is what every revolutionary cried since the inception of Marxism.
It's time to read this poster that warned you a half a century ago of the demise of the United States. Don't you think it's time to heed that warning? Or, is it too late?
