Even deeper: The American free-market libertarians pulled a coup when they were able to redefine, in public discourse, what it means to have 'liberty' (compare the definition of 'libertarian' ca. 1900 Europe and ca. 2000's USA).
Or the way the words "liberal" and "progressive" have been hijacked by people who actually believe in the USSR of the 1950s.
In what sense? The progressive movement as currently constructed is not enamored with neither Leninism nor Stalinism, though there is sometimes a smidge of respect for Trotsky.
