Mis-attributed to
Vladamir Lenin by Conservatives, (who usually learn of the term on social networks), it's used to degrade Progressive Liberals, who don't judge others from different countries, politics, or religions, as harshly as they do.
Conservatives often use the term to anyone who takes a different stance, whether the "useful idiot" is supportive of, or non-discriminatory toward: Socialists, Democratic Socialists, Democrats, Communists, Atheists, Catholics,, Muslims, Jews, Buddhists,
Masons, Blacks, Hispanics, Indians, Arabs, Native Americans, and Europeans.
Thus, "
useful idiots" are usually ignored, while they're blamed for "ruining" (ie. improving) a nation, and spreading love of others, rejecting discrimination, and equality treatment for all.
