You are right, they are two different things. Some of my ancestors came to America as indentured servants. My original patriarchal connection to Europe, was a man who was "Black Dutch" and he was among 23 others, who a wealthy Englishman provided passage for, in exchange for 10 years of their lives in his service. This was a common practice up North, perhaps even more common than slavery in the South, although the numbers of slaves was much greater.
The important thing to note is, we had not yet came to the time where "an honest day's work for an honest day's pay" had come to fruition. Where "liberty and justice for all" meant everyone in society, even if they didn't own land or have white skin. America was a very racist society by today's standards, and I think this would shock some liberals here, if they were to go back in time and experience it. A lot of things have transpired since 1964, and a lot of things transpired between 1865 and 1964. To pretend that in 1861, we were having any kind of 'national debate' on civil rights for blacks OR ANY PEOPLE OF COLOR, is absurd.
BLACKS are actually the most fortunate of ALL non-white folk, they have been placated to and catered to since emancipation...yeah, they had a rough time back during slavery, but since then, it's been all about them! Us poor Native Americans are discriminated against to this day, our lands were taken, treaties were broken, deals were reneged on, and we were marched half-way across the country to be put in what amounts to concentration camps. Your folks got 40 acres and a mule!
