useful idiot

Quote from Urban Dictionary (a lexicon whose vulgarity makes me laugh and one I do not recommend for children)…If you have never heard the term “useful idiot”, it was the attitude held by Vladimir Lenin towards communist sympathizers in the West (America).

While Lenin and the Soviets held them in utter contempt, they also viewed them as tools for dispensing communist propaganda to other countries, thus infecting foreign cultures with their totalitarian tripe. After their mission was complete, they were no longer “useful.”

It's a term the [sic] refers to brainwashed American Marxists who blindly support any ideology that gets themselves out of real work and causes others to pay their way.
