Correct me if I'm wrong.
Afaik, liberalism ambiguously meant both advocacy for human rights and an economic system. To avoid this confusion, the economic system has been moved out as libertarianism.
For example, accessibility improvements of government buildings is a liberal movement.
Minimizing the control over capitalism is a libertarian movement.
There's also so called "liberals" which is not more than a hate speech. We are not "conservatives" or "liberals" in every topic.
right-wing "libertarianism" is a non-philosophy
