Once upon a time, basic "Human Rights" did not exist for any one, any where. it was a "dog eat dog" world. Only if you were a King and had all you wanted could you get all you wanted. As societies grew, more and more people wanted freedom from tyrants who cared very little, if any, about the "lower class". Things got "ugly", but eventually peace was restored by granting rights to "men" with enough money to purchase land for their "sovereignty".
It then took a long time for the average person to win the right to own property. This new struggle "blew" the minds of the now very wealthy "controllers" of society. Why would a common place person want things, they asked.
What most people don't see is the relationship between the "Toilers" and the "Liesures". These two oppositely ended groups in a society are often formed by the same types of people and every society that has totally separated these groups has had "civil" war.
The United States Civil War was bloody, disastrous, costly, informative, ground breaking and it took over 100 years for it's message to be heard again. The Emancipation Proclamation was written in 1865 but in 1965, some one who's skin was darker than average "legally" could not interact, they were segregated. Most of us today have friends of another color, whom we wouldn't trade for the world. That is Dr. Martin Luther King Jr.'s Ultimate Dream come true.
Who really has the right to own what? That is the real question to be asked. Land, homestead, automobile(s), But to own a Human Being, you see, the word property can be defined in any way society wants.
The right to be treated equally is a battle we must all face. No one is safe from discrimination of any type because we are all different and exactly the same.
