Do you really, though?
You champion one system of very imperfect liberty -- a mix of liberty for some and oppression for others -- and you b*tch about another blend of freedom and unfreedom. Somehow you alone are better that that, and the rest of us aren't.
The world being what it is, and perfect liberty being an impossibility, a lot of people throughout history have felt that they deserved better with a lot more reason than you do now.
You may not have what you want or want what you have, but you don't deserve a better world than the rest of us, nor would you create a better world if you had your own way.
Nobody defends slavery.
