I find the qualifier "true" to be superfluous. For example, it suffices to say that "no vegetarian eats meat" without needing the qualifier "true," because (as you point out) the not eating meat is definitional to vegetarian. Same thing for "no atheist believes in God" and "no Christian believes Jesus isn't the Son of God."
Having said that, my response would be different:
JOHN: No vegetarian would eat meat.
SALLY: My friend is a vegetarian and eats meat regularly.
JOHN: If your friend eats meat, then your friend is not a vegetarian.
As it pertains to political discussions, it is patently absurd to suggest that "Libertarians want the entire of humanity to be their slaves" because such overbearing governance is precisely ANTITHETICAL to libertarianism, or the near complete opposite of what they champion. It is unnecessary to say that "no true libertarian" would support such a thing; totalitarian government is definitionally contrary to libertarian ideology.
