Certainly not perfect (especially not if you were black, Japanese, gay or communist), that would be a silly claim, but freer.
I'll agree with you that the civil rights movement beginning in the 1960s was necessary for the United States to extend the benefits of freedom to all its citizens. But universal suffrage for women came significantly earlier in the United States than it did in Switzerland, for example, and black people in my state (Minnesota) have always been able to vote and to own property and to marry whomever of whatever race and so on since before Minnesota became a state (which, indeed, was one of the points of the Dred Scott case, in which a slave tried to become free by claiming that his passage through the free territory of Minnesota should end his condition of slavery). The Civil War was a necessary reaction to totalitarian denial of basic human rights by the Confederate states, and the civil rights movement after World War II was a necessary response to the deplorable segregation that still occurred in those states long after the Civil War, but everyone in some regions of the United States has long recognized that slavery and Jim Crow segregation were both aberrations, gone in some states from the beginning, and always contrary to the basic principles of the Declaration of Independence and the Bill of Rights (and the bills of rights in various state constitutions).
I do hope that we can make a better future, but it is not like the past was the greatest thing either.
It's as if Mother Liberty was the Goddess herself: for whenever two nations come into a fight, people in both are always saying that "God is on our side"...
This is also why the concept of free will is so problematic: how free does will have to be to be called free will? Does it have to be free from the laws of physics? Does it have to be free from coercion?
I think there are more concepts where we have it the wrong way around like this.
Edit: thanks for the clarification, koningrobot,
I feel like free will doesn't have much to do with the kind of freedom we're talking about, though. If some other human being (or group) has the ability to make you do something you don't want to do, that's a problem of freedom, not free will. (After all, you could decide not to do that thing and suffer the consequences).
Free will is much more about things that you have no ability whatsoever to actually make that decision in the first place, whether because of the manipulative hand of some supernatural force, or via some radical rationalist explanation of decision making.
I understand the distinction you're making between freedom and free will; I mentioned it because the compatibilist notion of free will is what you're calling freedom here. But yeah, it's probably not too relevant to the original discussion.
By 1930, of course, the KKK had a significant political presence in Indiana, and at this point, white rural Hoosiers hate blacks with the best of them, but I was surprised to learn that that attitude came well after the end of the Civil War.
Point is, it's always been a fight.
