“We discovered a rampant amnesia about the crimes munist regimes,” says Marion Smith, “and a growing inclination among younger Americans toward favorable views munism and socialism.”

Their latest survey was recently released—and the responses are just as troubling:

• 7 in 10 Millennials (like most Americans) either don’t know the definition munism or misidentify it for socialism.

• 7 out of 10 underestimate number killed munism. Less than one third know more than 100 million people were killed munism.

• At least one-in-fiveMillennials munist leaders favorably: Che Guevara (31 percent), Karl Marx (32 percent), Vladimir Lenin (23 percent), Putin (21 percent), Mao Zedong (19 percent).

• More Millennials (44 percent) prefer to live in a socialist country than live in a capitalist country (42 percent).

• Of all Americans, Millennials are the least unfavorable munism. Only one in three (36 percent) have a “very unfavorable” view munism.

“Communism isn’t back: It never left,” says Smith. “We simply forgot about it. And as it rears its ugly head once more, openly and shamelessly, we seem far less prepared to meet the ideological challenge in this pared to the last.”
