There are two types of freedoms under liberalism, the "freedom to", and "freedom from". Libertarians are mostly concerned with the former (e.g., minimising laws which stop their ability to do something) whereas modern liberalism takes a more balanced approach (for example, making racial discrimination illegal reduces someone's freedom to be racist whilst improving another groups ability to partake in society without experiencing discrimination)
> The american definition of "liberal" basically means socialist.
No, it doesn't.
Though it overlaps with a common American use of “socialist” to mean anyone outside of the far-right. Most American “liberals” are center-right corporate capitalists, which is also the narrow sense of “liberal” in much of the world.
> In 2020, "liberals" in america have very little to do with the original meaning of the word which meant "in favor of freedom".
This is false, and even more than just being liberal in this vague sense, most American “liberals” and a great share of American “conservatives” are adherents to ideologies which evolved fairly directly from 18th century classical liberalism, differing largely in whether they view the immediate goals of 18th century liberals as having been terminal or steps in the direction of the desired goal.
You are technically correct. The distinction lies in the way the followers of these ideologies understand their philosophy. Libertarians in America are all about liberty from government. For them ideally government is super-limited. Liberals are better understood in terms of traditional thought. Conservatives wish to conserve the “traditional way” of thinking, living, and organizing society while liberals want to “liberate” humans from the those “traditional” ways.

Your statement is true but Democrats, who call themselves liberals, are not that. They are the most conservative party. They're much more conservative than Republicans on most issues. For example, ideas about "science" or "nature" for example.
Those two are words whose meaning morphs over time and every person seems to have their own pet definition so the terms are essentially meaningless and become whatever anyone wants. I've heard people to the left of Sarah Palin being described as liberals after all. These two terms are heavily misused.
We're pretty much in a double-speak world right now.
