Apparently in your dictionary the words “liberal” and “libertarian” are interchangeable. Please consult the dictionary the rest of the world uses.
You must have next to that dictionary a rather unique history book where the Libertarians overthrew the czar and created communist Russia. Be assured, the author of this dubious book is quite alone in that theory.
This might give you a clue as to what my post was saying apart from you linguistic and historical flights of fancy...I’ll make it simple for the bibliophobic. Liberty. Libertarian. There’s a reason the words sound so much alike. Libertarians reserve the right to refuse service to anyone, and people have the liberty to seek other services or provide the service they prefer. Liberals would codify who you could serve and who not, reserving power for themselves. This is repetitive echo of my original reply; it is evident you do not read the posts you comment on.
Not interchangeable, but I do know that libertarianism originated as a leftist philosophy and evolved under its auspices.
It's actually the leftist movement that predates Marx, and is the one that he and Engels sought to perfect a philosophy for its implementation.
