Social liberalist, progressive, marxist...
Need I say more?
Except the term liberal could be confused with Classical liberalism, therefore I think we need to fine tune the definition of the leftists and either call them what they have clearly demonstrated themselves to be, leftists or Marxists.
They’re not Progressive if they want to lock everybody in the chains if fiscal bondage.
Call them Authoritarians or Statists! It’s accurate and covers the Fascism & Communism\socialism adherents.
