I like “Holier Than Thou Hypocrites,” it captures their self righteousness perfectly.
The line between liberalism and socialism has become increasingly blurred, when I was running as a candidate for the UK Liberal Party in the 1970s and 80s the party stood for localism, devolution of power to regional authorities and minimisation of government. Labour, the socialist party stood for state control, high taxes and bureaucratic intrusion into the minutaie of provate life.
Now both support global government, massive social engineering projects (i.e. mass migration) to disrupt national cultures, and state control of what we are allowed to think and say.
Limousine Liberals is a tad obsolete however, these days they’d rather ride in a chauffeur driven Toyota Prius.
